Hi - I am trying to decide between these two tires. Bridgestone Potenza
S-02 Pole Position vs. Yokahama AVS Sport. I live in the Bay Area
(California) so I don't see any snow, just some rain. Mostly use the car
to commute so I would like something that lasts and performs well.

Thanks

Keep in mind that "performance" and rain dont go well together.

You'd not have a problem with any of those tires in the rain as long as
you adjusted your driving to fit the weather at the time.

Not saying you cant get a performance rain tire, but most ppl when I hear
they get some..still drive like its a dry day.

I get a fair amount of rain where I live and love the performance
of the Potenza S-02.  I have used them for three years now and
have no trouble whatsoever in heavy rain (I would say that is a
perfect wet weather tire).

I need to change the front tires every 12 months, and the rear
every second time I replace the front.  For example I purchase
two tires, then four, then two, etc, every twelve months.  The
Potenza S-02 Pole Position (225/55-16) cost NZ$390 (US$164)
over here.  I run the tires on a '91 GTO-VR4 running 1.05bar
(15psi) boost without slippage in the wet (maybe I am not
punching it hard enough?).

Hope this helps,
Cheers,
Kevin.

You may want to check also the Firestone Firehawk SZ50 EP.  It's cheaper
than Potenza and wears longer, but with a very high dry traction rating.

Hi,

I hear a faint squealing sound every once in a while that seems to come from
the front right wheel area, I thought it was the brakes but I took the pads
out and cleaned the silencing pad put some brake grease(don't know what it
is called got it at Auto Zone, supposed to quiet noisy brakes) on the back
of it and cleaned the rotor and caliper assembly with brake cleaner.  This
did not seem to help the problem, what could this be?

Subject: Team3S: Brake Kit Discount Available

Hi All,

I am passing this along to all interested as a favor to a friend that
has provided a lot of his expertise in brake kit upgrades to me over
many months which has consumed a good bit of his time. He is the North
American Distributor of Mov'it North America and his site is
www.ultimategarage.com (big brake kits). He is extremely knowledgeable
re: Porsche brakes and Mov'it is the largest customer of Porsche brake
components which has afforded them many benefits. They test many new
components Porsche is developing and even though they state kits cannot
be broken up, Steve seems willing to consider this. eg. He can get us
Porsche 993 Turbo rotors which retail (last I checked in CA) for $216 a
piece for $175. These are the best rotors available, but unfortunately
require hats machined specially by a shop out of steel for ~$400 or they
use 7075 aircraft quality lightweight aluminum (very tough) for $700.
Unfortunately kits with rotors, hats, calipers (extensive machining done
here too), pads, and lines are available for 93 and above 3000's/stealth
currently. that leaves me out:(. I pass this on since some have asked
for good Porsche information re: brakes. this site has good info. Check
out FAQs under big brakes. Steve is interested in giving discounts to
any as a model for this kit and want to take pictures, etc. to help
advertise this kit. Most of the market is Beamers, Porsches, etc.. FYI
Hans Stuck is a big customer. At 245 on the Moulson straight (SP?)
braking to under 100 I think he knows his brakes. Other sites I have
passed on are:

www.rennsportsystems.com (excellent Porsche info as well as brake fluid
comparisons etc.)
The other Mov'it sites (German site (their headquarters) and the North
American sites are also linked to UltimateGarage.

Hope this helps

Subject: Team3S: turbo leaking

This origional question was asked by Chris Maxwell in
regards to his boosting problems with his 355 gtpro turbos.

Those pictures depicts the manifold heat shield covers.
It is unlikely that you'd crack the exhaust manifolds themselves as
they are pretty thick, unless you got into an accident.

You'd have to remove the covers and the manifolds to be sure.

I'd start with the gaskets used when the 355's were dropped;
they all need to be new and torqued to specs.
You might just have a few loose manifold/turbo bolts.

Aside from that, inspect your wastegates.  They need a lot of force to
hold them in place, and if they're weak, you'll get premature boost leak.

Good luck,
Noble

Subject: Team3S: porting question

Hey everyone,

I've read about DSM's porting their exhaust manifolds for more airflow.
Since I've got mine out, should this be done?

I noticed that one of the turbo gaskets on the DSMs is round to guide
the turbo into place.  What some guys do is machine out the entire gasket
as well as the surrounding area for more airflow.

Sounds like a good idea, but what about sealing?  To those that have done
this and driven their 3000/stealths under full boost, have you had any
problems simply running on 1 flat gasket instead of 2 gaskets, like the
factory
recommends?

Thanks in advance,
Noble

Michael,

I have the S02s on my VR4 and have been a loyal fan of Bridgestone for 4
years. Those S02s work well in the rain. I used them to get thru thick snow
on some of the mountain passes here in Washington State and it was real
impressive. Of course, the AWD on our cars helped the most! :) The S02 pole
position is available on most sizes except the one set I am currently using
which is 265 35/18. The pole position is suppose to have another sticky
layer beneath the thread so that if the main thread wears, the sticky
substance will still allow you to grip the road. Honestly, both the S02 pole
and non pole position have that, so you shouldn't have to worry.

Hope this helps.

You could skip the ring gasket and port the steps for that ring out of the
exhaust side turbo inlet and the manifold.  I don't think you'd really see
any difference in airflow though, as this area isn't any more of a
restriction than the rest of the manifold, and it would restrict back down
to the same diameter as it enters the turbo.  On the other hand, it
shouldn't hurt anything.  Should be okay to go without the ring gasket
installed, however you'll need to make sure the turbo is mounted to the
manifold exactly on-center which will be difficult without the ring gasket.
If it isn't perfectly centered then you'll be introducing a worse
restriction than if you had the ring in place.

The ring gasket isn't really sufficient to seal anything, so the flat crush
gasket is already doing all (or most) of the work.  Should be okay, but keep
in mind that you don't want to be taking this stuff apart again so if
there's any question about it then you might want to skip it.

Hi Chris,

I assume you mean exhaust manifolds. As noble pointed out, the
"crack" is in the heat shield in the pictures you posted. If you are
developing boost at all, more than likely the exhaust side of the
plumbing is working just fine, at least for one turbo. The most
likely reason your turbos only develop 0.4 bar of boost is because
all of the boost reference pressure from the Y-pipe is going to the
wastegates and they are opening just like they should. Wastegates
stuck open then no boost. Wastegates stuck closed then (possibly) too
much boost.

Our wastegates will fully open when they "see" about 6 to 7 psi of
boost (0.41 to 0.48 bar). The only way we can develop higher boost
than that is too fool the wastegates into staying closed longer. In
other words, we either restrict or bleed off pressure in the boost
reference hose from the Y-pipe; the wastegates "see" only 4 psi,
let's say, of pressure when really there may be 8 or 12 psi of
pressure in the Y-pipe. I think you should look carefully at every
piece of your boost control system from Y-pipe to wastegate - every
hose, every connection, and the boost control solenoid (stock or
aftermarket) - for the source of your problem. Take out the battery
and washer tank (see my Garage web page for tips), and the MAS/air
filter to get a clear view of all the intake hoses and devices. Now
if you were developing no boost at all you could suspect a major leak
somewhere (like a loose/cracked IC pipe), but the 0.4 bar number
suggests the wastegates are "seeing" all of the Y-pipe pressure.

As a semi-dangerous test, pinch closed the pressure hose that goes to
each wastegate and see what happens. Boost should go way up as the
wastegates never see any pressure signal to open.

Subject: Team3S: Steering wheel affects oil pressure gauge

I notice when the car is warm or cold, that when I turn the steering
wheel, the oil pressure gauge in my '92 TT will peak at high.

Does anybody else observe this phenomenon?

Does anybody have an explanation? I suspect the problem is electrical
in nature as I don't see how the oil pressure can rise dramatically
without a rise in RPM (crankshaft speed that turns the oil pump).

I have looked at the manuals and it appears to me that
(1) the wire from the B-36 connector (oil pressure gauge unit, OPGU)
goes directly to the combination gauge (not ECU),
(2) the power steering fluid system is closed and seperate completely
from the engine lubrication system,
(3) the PS fluid level sensor goes directly to the warning light (not
ECU), and
(4), the steering wheel position sensor (SWPS) output goes directly
to the ECS control unit (not ECU).

The OPGU is a variable resistor that sends higher voltage to the ECU
when the internal contacts are kept closed longer (when oil pressure
is higher). The only electrical connection to the power steering is
the 4WS fluid level sensor (an on/off switch). Now there is a sensor
for steering wheel position by the steering wheel but I don't see how
this might affect the OPGU voltage as the OPGU does not go to the ECU
that I can see - maybe it does - and neither does the SWPS voltage -
maybe it does to. Have I missed something?

Any ideas for this weird "problem"?

Thanks,

Ahh check it out - this one is alot easier than you would think.

Try sitting inone place and turning the steering wheel.  Now closely observe
the RPM gauge.

The engine actually idles up a bit whenever you turn the steering wheel, to
allow the power assist to actually do its job.

That's the reason the oil pressure raises.

Does anybody have an explanation? I suspect the problem is electrical
in nature as I don't see how the oil pressure can rise dramatically
without a rise in RPM (crankshaft speed that turns the oil pump).

I have looked at the manuals and it appears to me that
(1) the wire from the B-36 connector (oil pressure gauge unit, OPGU)
goes directly to the combination gauge (not ECU),
(2) the power steering fluid system is closed and seperate completely
from the engine lubrication system,
(3) the PS fluid level sensor goes directly to the warning light (not
ECU), and
(4), the steering wheel position sensor (SWPS) output goes directly
to the ECS control unit (not ECU).

The OPGU is a variable resistor that sends higher voltage to the ECU
when the internal contacts are kept closed longer (when oil pressure
is higher). The only electrical connection to the power steering is
the 4WS fluid level sensor (an on/off switch). Now there is a sensor
for steering wheel position by the steering wheel but I don't see how
this might affect the OPGU voltage as the OPGU does not go to the ECU
that I can see - maybe it does - and neither does the SWPS voltage -
maybe it does to. Have I missed something?

Any ideas for this weird "problem"?

The oil pressure sender connection is very close to the steering system
(rack and tie rods)  Take a look under there and see if the wire has worn
through.  If the connection was loose the gauge would drop not rise.  Seems
like a short to ground would give you a max oil pressure reading.

Subject: RE: Team3S: Steering wheel affects oil pressure gauge

Thanks Cody. Nice idea but I checked that out already. I observed the
RPM when I turned the steering wheel and no significant increase.
Also, I revved the engine a lot with the steering wheel straight and
no (big) oil pressure increase. The oil pressure gauge literally
pegs, not just raises up a little, when I turn the wheel - even while
driving.

Any other ideas?

Thanks,

Ahh check it out - this one is alot easier than you would think.

Try sitting inone place and turning the steering wheel.  Now closely
observe the RPM gauge.

The engine actually idles up a bit whenever you turn the steering
wheel, to allow the power assist to actually do its job.

That's the reason the oil pressure raises.

Subject: RE: Team3S: Faint squealing sound that comes from the front right wheel area

[Willis, Charles E.]  Does the squeal happen only on applying the
brakes, or while the wheels are rolling?  If you hear the squeal while
rolling, not only on braking, you might be hearing wheel bearing noise.  I
don't believe you can replace or repack the wheel bearings - you have to
replace the whole hub.  If you have to replace one side, you may as well do
both sides.

Does the squeal happen continuously during braking, or does it go
"squeak, squeak, squeak"? - that might be a warped rotor.  I didn't notice
whether you had the rotors faced off (machined/milled/turned).

What kind of brake pads are you using?  Highly metallic pads (like
PAGID) squeak a lot in normal use, even when the pads are new and the rotors
are flat to within 0.002".

Does the car stop good?  Or does it pull to one side?  What
condition were the calipers in?  Did the dust boots on the caliper pistons
look good or ragged out?  If a piston sticks after you release pressure on
the brake pedal, it can leave the pad in contact with the rotor.  Over the
years, these chrome pistons get corroded, and you have to clean them or
replace them while rebuilding the calipers.  Also the seals on the pistons
tend to swell up and can make the pistons stick.

When was the last time you drained and bled the brake system?  The
fluid wouldn't directly affect the squeal, but old fluid picks up water
which causes corrosion.

Brakes are a good thing!  Everybody concentrated on horsepower, but
stopping my two-ton monster is very important to me!

Michael,

The wear on the S02s are not as bad as they deem it to be. I have had my
present tires for 2 years and I still have quite a bit of thread left on
them. I bought them when my VR4 had about 90,000 miles. I now have exactly
119,020 miles on my car and it is still alive and well. I don't know the
exact amount but you still can see the V pattern very clearly on all 4
tires. Inside thread (near the strut tower) seems to be good too. Actually,
my feel to this is that it depends on the alignment of the vehicle. I have a
friend with an RX7 with these same tires on his rear. He has extremely
negative camber on his rear and he goes through two rear S02 tires - 265
35/18 every year as the inside balds quickly compared to the outside. :)

Tire wear for the S02 also depends on how often you drive your car. So far,
I drive it very often and it has still held up pretty well in terms of
thread wear.

Average life span of these tires would depend on how much u drive - I would
say 3 - 31/2 years or 60,000 miles. Again, I cannot emphasize enough the
point on regular alignment and how often you drive and the distance
traveled. The Yokos are suppose to be equally good and like you said,
suppose to have longer thread life. All in all, I have heard from some of my
friends who tested out the Yokos and concluded the S02s are still better.
Some tires stores like Discount Tire will tell you that S02s are over priced
and not as good as Yokos. Beware; As Discount Tire and other stores say this
becos they get more commission selling Yokos than the Bridgestones. They
will tell you anything just so that they can sell the tires which make them
more commission. !!

So, the main thing here is to go with the tire you like best and not so much
who is telling you what. I have personally stuck with S02s for a long time
and will continue to recommend this tire as long as it is in production. I
don't think you have to worry so much about thread wear - as long as it
GRIPS the road and keeps the driving safe! That is real important in
Seattle, where it rains alot. Even the Bridgestone Blizzak snow tires are
ranked no.1. I plan to get those for my other car if a freak snow storm hits
Seattle again this year.

Both tires look good from a distance so I know how you feel. It is a tough
decision. You will have to give both a try if possible to really know for
sure which tire is more suitable for your driving habits. Try the S02s and
they will last for some time. If they don't, please don't chew my head
ff  - lol. But instead, try the Yokos. I am sure you will like the S02s -
and I am not getting commission for neither brands. :))

From: Ken Middaugh <Kenneth.Middaugh@gat.com>
Subject: Team3S: Brake summary (long), was: Brake Kit Discount Available

As you may recall, some of us track and "decelleration" enthusiasts banded
together in search of better, resonably priced brakes for our cars.  There are
already lots of kits available for our cars, but most are expensive.  We wanted
something that was economical, yet was a big improvement over stock brakes.  Our
original goal was to fund research and development of a 2 piece rotor for Brad
Bedell's Porsche "Big Red" upgrade kit.  With a 2 piece rotor, Brad's kit would
be very similar to Mov'it's $2800 kit but we were hoping that Brad's kit with a
2 piece rotor would be about $2100.  A lot of investigation was done and here is
a summary.

We ended up not spending any money on R&D since our investigation uncovered
existing economical solutions.  It turns out that there would be little if any
cost savings if Brad were to fabricate his own hats for 2 piece rotors versus
just buying them from a reputable and experienced manufacturer.

FRONT KITS
$1450
Brad's Big Red kit, http://home.austin.rr.com/overboost/.  It currently sells
without rotors but includes Porsche 993 calipers, caliper mounting brackets,
Goodridge stainless steel brake lines for 4 wheels, a set of pads, and fluid.
This is the entrypoint to serious brake upgrades and folks have reported
dramatic results.  With a set of $250 Porterfield rotors you can seriously
upgrade stock performance for about $1700.

~$1900
KVR "Lobster" kit (his name for the Big Reds) with 2 piece Porsche rotors.
Terry Gosse of KVR, http://www.kvrperformance.com, has been doing custom brake
kits for many years and has a lot of knowledge and experience.  Basically, he
can do anything for any budget.  This price was approximate, and includes
Porsche 993 calipers, mounting brackets, 2 piece rotors using Porsche GT2
322x32mm disks and custom 6061 T6 aluminum hats, stainless steel lines for the
front, AP racing fluid.  I don't know if this price would include SS lines for
the rear, or include pads.  However, this is basically the same thing as the
Mov'it kit for a lot less money.  Porsche makes awesome disks.  They are
directionally veined, the holes are cast and then drilled to final diameter.  If
desired, he could substitue other, larger disks for about the same price.  KVR
also has directionally veined disks that you can get solid, crossdrilled, or
slotted.  The Porsche and KVR disks have "reasonable" replacement costs, less
than $200 each.  The hats should last 5 racing seasons or a lifetime on the
street.

~$2100
KVR "Big Black" kit with Porsche 928 S4 calipers with 2 piece rotors.  This kit
is the same as the above Lobster kit except for the calipers.  Terry Gosse of
KVR says these calipers will be a better match for our car since the 928 is a
similar heavy weight, front engine car like ours (VR4).  The Big Red calipers
are for lighter, rear engine cars.  The Big Black calipers have 2x38x44mm
pistons while the Big Red has 2x36x44mm pistons.  This extra 2mm makes a big
difference over 4 total pistons.  Also the Big Black calipers are bolted
together more near the centerline and will deflect less than the Big Reds.  The
Big Blacks use shorter 50mm pads which deflect less than the Big Reds 60mm
pads.  The Big Blacks can accomodate 332mm rotors while the Big Reds max size is
322mm.  Finally, there are more pad choices for the Big Blacks versus the Big
Reds.  This is IMHO the best deal of the survey.

~$2200
Stillen Brembo kit, http://www.stillen.com/brakes/systems/systems.html.  This
was the price a few years ago.  Some folks have this and are very happy, but
others have reported that their crossdrilled disks crack and warp.  The
replacement disks are also costly.  Supposedly, the Porsche treatment of Brembo
calipers in the above kits is better than the stock Brembo caliper in this kit.
The calipers do compare to the 928 though since the pistons are also 2x38x44mm.

~$2100 - $2800
Mov'it Big Red kit, http://www.ultimategarage.com. The Ultimate Garage's web
site say they utilize the Porsche 996 monobloc calipers (instead of the 993) and
the GT2 2 piece rotors.  These 996 calipers would make it better than the above
Lobster kit.  Supposedly, our European friends can get these directly from
Mov'it for about $2100 although Ultimate Garage's price is $2800.  I think Roger
Gerl was investigating becoming a Swiss distributor.

$2500 - $3000
KVR AP Racing 6 piston caliper and 2 piece rotors.  Terry said he could sell
this kit for $2500 for a group purchase of 5 or more.  $3000 is the normal
price.  I'm not sure if this is the identical kit to the one on Stillens web
page.  This is the entry to the "very serious" upgrades and is really a step
above the previous kits.  It can accomodate 355x35.5mm rotors!

$3000+
There are other kits available but not investigated becasue of their prices.
Mov'it's Terminator kits (14.9" disks!!), Baer, and Wilwood, come to mind.
Probably the awesome looking NewTech fits this category too.


REAR KITS
~$1800 - $2600
Mov'it has a kit for the rear brakes too.  It uses Boxter S components including
a 299x24mm rotor.  It should cost about $1800 in Europe but $2600 in the states.


SUMMARY
All of these kits including the Mov'it kits should fit '91+ 3000GTs and
Stealths, as long as you have the wheel clearence.  To improve clearence and
increase front track width (reduces understeer), you could utilize a thicker
facing on the hat with longer wheel studs.  Since Mov'it is now using 996
calipers, it would be worthwhile to compare them with the 928 S4 caliper.
Regardless, Terry Gosse of KVR should be able to build custom front kits with
any caliper and any disk and still have  unbeatable prices.

Happy braking,
Ken

How many miles on your car?  It sounds like the wheel bearings to me.
Sometimes when the wheel bearings are going out, the wheel only squeals when
you put it under load, like while turning or braking.  The bearings in my
son's VR4 went out at about 80K miles.

I would remove and turn the rotors first.  It's a lot cheaper than replacing
the hubs, unless of course, you have an extended warranty.

The pads sound kindof like CarboTech Panther Pads.  Were the metal backings
on the pads painted gold?

Tire wear depends much more on *how* you drive, not how often you drive.  If
you just tool around on the freeway, you aren't going to get much tire wear.
If you drive aggressively and corner hard, the tires are going to wear much
quicker on the edges.  You said you can get 60,000 miles out of a set of
tires which, frankly, for a performance tire is abnormally high.  Even on
long wearing tires, I max out at about 30,000 miles by the time the edge
tread is worn beyond usability no matter what the type/construction/brand.

Thanks to Edwin Shaw, we've found a source for Brembo rotors.

Here's the description from MVP Motorsports:
Brembo Cross-Drilled or Slotted Front Rotor for 3000GT VR4, 1993.5-99 
 
 This is for all VR4's made from 6/93 to 1999. Price is per rotor. These
are direct replacements for your stock rotors. They are the same size and
fit under your stock calipers and your stock wheels so no other upgrades
are necessary to use these rotors. Remember, this is Brembo quality, not
some generic brand slapped on a drill press with holes punched at random.
Every rotor is cadmium plated to prevent rusting. Each rotor has been
X-rayed and is of the highest quality metals. PLEASE CHOOSE DRILLED OR
SLOTTED UNDER
ITEM # Br FR VR4 93-99  
MSRP $224.00
Your Price $190.40

Seems like this is exactly what we've been looking for, n'est ce pas?
Because they are Brembos, we can order them drilled, too.
Does ANYONE have any experience with these on a race track?

Rich,

Why would this not fit the 91-92 models? Does the Big Red kit fit 91+ models
if the wheels offer enough clearance?  Would the Brembos fit 91-92 models if
we convert to the Big Reds and have larger wheels?

For 1 piece steel rotors, I agree.

However, #1 and #2 will cost $1700.  For a few hundred more (~$1900 or so) you
can get the KVR Lobster kit that has the same calipers and a 2 piece rotor using
the Porsche GT2 disk.


> 3. The next upward step MIGHT be to buy a two-piece Porsche rotor.

A 2 piece rotor would definitely be the next upgrade.  Here are some of the
advantages of 2 piece rotors:
1)  They are lighter.  Not only do they reduce the weight of the vehicle, they
reduce the important un-sprung weight (lighter wheels do this too).
2)  Higher performance.  There is no doubt that cross drilled and/or slotted
rotors provide better braking.  If the Porsche rotor resists or eliminates the
usual tendency for cross drilled rotors to crack, this would be a great
advantage.
3)  Better cooling.  The Porsche and KVR rotors (and Supra too) have directional
cooling veins.  This will increase the longevity of the disks.
4)  It is possible to manufacture the hats with thicker facings.  This
essentially provides an integral spacer to increase the front track and/or
provide more wheel-to-caliper clearance.  Longer wheel studs are required.

Some advantages of the Porsche disks are:
1)  Holes are cast and drilled out to final diameter.  This means they will have
less of a tendency to crack than other cross drilled rotors.
2)  They have directional veins.  This will improve cooling and prolong the life
and performance of the rotor.

Also available would be KVR's directionally veined solid, cross drilled, or
slotted rotors, probably available in more sizes too such as 332x32mm.

Basically, thats a lot of advantages for a few hundred dollars more!


> (Does

Most likely, unless your current rotor is 322mm in diameter.  Folks ordering 2
piece rotors should also order caliper mounting brackets.  Unfortunately, this
becomes an expensive upgrade in the two-step approach, likely around $850.

Agreed.

Yes --- I have the Big Red setup with 1994 17" wheels on my 93 Stealth TT.

I also put one of my 1993 17" wheels to see if they would fit, they did but
with about .010" clearance on one side, in my opinion not enough
clearance to race with.

I've said this a couple of times in the past --- porterfield will make custom hats [ about
$300 each ] and damn near any rotor configuration you want. The rotors were about
$110 plus $40 for cryo treatment.

I still remain unconvinced that cross drilled or slotted rotors provide any advantage for
us, even at open track events. The purpose of the slots/holes is to allow gasses to escape
under heavy braking, the main problem with our cars is overheating and burning up pads
or boiling brake fluid. If you want to spend money, do it on cooling goodies [Merrit style],
air ducts, fans, water, and wheels with open spokes. Once a certain level of performance
is achieved, additional efforts to shorten stopping distance are a waste of money. At this
point cooling the brakes should be your priority.

I agree, but take a different view of braking finances. I want to
optimize my large pad surface area and therefore need larger rotors then
anything stock Porterfield would make except venturing into a non-stock
rotor which means customization anyway. To get the 332x32 SA I think the
Cast Porsches are unmatched. I am willing to pay for the development
costs. My solution to the rears are is going to be a bit creative, but
will be upgraded rotors and calipers, right now probably stock fronts. A
master cylinder upgrade will be critical to making this combination
effective. A 24 mm MC or around there will be necessary. You can get
kits with hats for the Porsche rotors, but my post 93 Stealth dosn't
have the bolt on kits available for the post-92 models. I am also
willing to pay for the strong stuff. Which means 7075 aluminum. No
cracked hats hear. All in all my kit which is a smorgasbord includes
F-40 calipers ($1050), Porsche rotors ($250), Machined 7075 hat ($600-
done by local shop) = $1850 total.
