While the brackets I use are made of 7075 aluminum, I feel they are much
stronger than the spindle they attach to.  I based my design on the stillen
kit's brackets and made them 'larger', thus stronger.  I kept the caliper
tight and the choice of rotor OEM to reduce any potential problems that I
can't foresee.

I  certainly can see the need of a government to set rules for safety in
their automobile.   There are times I wish our government would tighten the
rules to remove some of the 'road hazards' from our streets.

Please keep in mind that the Swiss goverment, as would many others, are
being extremely conservative.

I certainly do not accept their numbers as gospel.  I have no doubt that
there is a sound engineering foundation in what they are doing, but that
does not mean that in practice a particular rejected design will not work in
real life.

Brad's brake kit and the cars using them are holding up so far quite well
from what I can see, and under rather high duress conditions.  Whether it
stands the test of time will be proven...well...over time.  I see no reason
not to use his kit.

There isn't a lot to argue about really.  The theory means little if it
cannot be demonstrated somehow one way or the other.  The empirical evidence
so far suggests that Brad's kit is as good as any other.

And I believe you are right.  The driver controls the amount of pedal
pressure.  Brakes that are "too powerful" and used extremey aggressively
will cause other practical issues rendering them unusable far before they
have a chance to buckle the suspenion of the vehicle.

You're right about those rubber piston seals. The inboard pistons must do
the most work, or at least run hotter, because those were the ones with the
melted seals.

I use a similar technique to yours with the big Channellocks, changing one
pad at a time. I learned that lesson in basic hydraulics a long time ago on
my TR-3. Nothing like popping out a piston to slow down your pad change!

By watching the pit stops at Daytona and Sebring on Speedvision, I see the
racers now have brake piston depressor tools that push all the pistons in
simultaneously. Pretty cool--and fast!

The cordless drill is a great idea. I'll take one this weekend--along with
my spare pads and my stopwatch to time my pad change :)

Don't trust those torsion extensions the tire stores use. They can be WAY
off their rated torque. A real torque wrench is the only way.

Before I figured out how to handle the pad change, I looked everywhere for
one of those tools. JC Whitney had one, but it required a hole or a notch
in the pads, like on domestic cars.

No argument in regards to Movit kit they are WAY to expensive mostly due
to the higher grade aluminum they use in their kits. I find it way too
much and not sure how much the 7 versus 6 aluminum really makes? Anyone
Know. They claim it makes a big difference and is much harder to work
with therfore the inflated cost. I found KVR more knowledgable and ended
up coming away thinking the extra cost didn't justify the higher grade
aluminum.

The difference can be mostly attributed to how much flex the caliper &
adapters have when the pads hit the rotors.

The more flex you have, the less braking efficiency you have because the
pads wont push against the rotor evenly along the face.

I own a lotta cars.  But in the best interests of not having to continualy
edit this file to meet the needs of eight specific lists, and no to awaken the
idiots within others who think -thier- cars are the best and Im a fool for
having anything -but- thier kind of car..I have not listed them.  If Im on
the list you are reading..I have one.

Richard,

I am not sure which 6xxx Al alloy you are refering to but here are the
numbers on the 7075 Al:
YS: 95 Mpa
Shield Strength: 150 Mpa
Hardness: 60 (HB500)
Thermal Expansion: 23.2 (10-6/ºC)

other data is available at http://www.efunda.com

The UTS is probably not as important in this application as is the fatigue
life of the metal.  Is the braket shot peened?  If I were going to put the
kit on my car I would definitly like to know that it has undergone extensive
testing.  If the kit hasn't failed in use to date then if it were to fail it
would likely be due to fatigue.  If the right metal is selected the failure
should be preventable by visible inspection.

Actually, I was referring to the width of the rotors in the AP kit which are
indeed 35.5 mm.  The point that I was intending to make is that these 35.5
mm wide rotors should provide better cooling, more resistance to warping,
and be less likely to fade than the more common 32 mm wide rotors.

The AP rotors also come in a variety of diameters.  I'm not sure which
diameter rotor the AP VR4/TT kit uses but it might be (coincidentally) 355
mm.

I don't doubt that it is possible to break suspension components with rotors
greater than 322 mm in diameter when using high grip track tires.  However I
think it's likely that one will obtain better braking (same stopping force,
less warping and fading, longer pad life)  using the larger AP kit and
operating it at something less than it's maximum capacity, perhaps at
85%-90%, VERSUS using a Big Red kit with a 322 mm rotor and continually
using it at 100% of it's capacity.

I wish I had the money to find out :).

Wouldn't it be possible to make stronger suspension components?
Has anyone made ducting to get cool air to our brakes like many cars have?

Go to www.bazillionbooks.com, scroll down to Racing Photos, click on
Heartland Park Nov 2000 to see a set of ducts for cooling brakes. These are
rather expensive, since they are made of space age plastics, but you'll get
the idea.

Subject: Team3S: Turbo / HP goal

first of all, who has the most hp?

I know this is a general question, but when we rate hp
on our cars, are we talking about to the wheels.. what am i pushing
on the ground?? or is it to the crank???

So it leads to my next question.. i have stock 9bs now and want to upgrade.
I guess my long term goal is probably to have a 500-600hp car. which isn't much
considering the extreme people out there... Anyway, what turbos aare going to
suit me best for those goals, considering id like to upgrade slowly.
Id like to have a set of turbos that will let me up to 14psi, but then as i get
more details on the car, keep upping the boost to give that 500-600hp.

are the 15gs good for this, or is it recommended to jump right into other
turbos that GTPro offers. like the 357's or the 399R's or the 368sx, or simply
the 15g.  Honestly what is the difference between all these guys?

Thanks
Mark

i'm pretty sure that you can go to your local auto parts store and get a
replacement.  just ask somebody at the counter so they can look it up in the
