The only mod on my car since the last time I went to M'town is the custom
catback exhaust. The car seems to leap off the corners better in 2nd gear,
perhaps because it has faster throttle response and faster turbo spoolup. I
can't find my post from last year when I reported my lap times but, as I
recall, I was in the mid 40s on the Kuhmos and Blue pads. This time, my
best lap was a 42.18 on street Michelin Pilots and street brakes. If race
tires and brakes are good for 2 seconds a lap, then it looks like the
custom exhaust helped pick up a half-second or so, and might drop me into
I gotta do better, because my nemesis in a TT AWD Porsche runs 38s on
sticky tires (41.5 on street tires), so I gotta find another second. I've
beaten him before, but now that he has sticky tires, the Porsche remains
just out of reach. I am a teensy bit faster through the twisty bits, but
with all that horsepower he pulls me a car length or two down the straight.
Time to reach into the horsepower bucket and find 50-75 hp.
My increased camber really helped tire wear. I can remember cording a set
of tires in one day at M-town. Now that I've gone to -3 deg camber, it has
stopped eating the outside edges down to the cord. In fact, the front tires
were wearing on the INSIDE more than the outside, leaving a two-in. wide
ridge just slightly higher on the outer shoulder (Geez, they were noisy
out on the highway afterward!) You can feel the wear by running your
fingers in from the outer shoulder to the center. It feels smooth going in.
Pull your fingers back on the tread, and you feel lots of sharp edges. They
are supposed to wear back evenly after some street use. The street
Michelins are showing no other signs of abnormal wear after the track workout.
My daughter drove the VR4 for 30 laps over two track sessions, and I got to
observe. I noticed some hop-hop-hopping when it hit bumps, so I guess this
means it's time for shocks. I'm still working on getting Penske to build me
a set of shocks, but progress is glacial. Guess it's racing season. Any
word on the availability of GABs these days? Is it still 3 months to get a
set? Is anything else available out there?
By the bye, she was turning 44sec laps in my car, so she's catching up. I
know that my kids will beat my times one of these days -- it is the nature
of things -- but I am not going to make it easy for them.
