For TTA (timetrials class A) and the coresponding PTA race class (same modification rules as TTA, but actual wheel to wheel racing) A C5 Z06 Corvette can have a minimum competition weight of 3118lbs. Min comp weight is the weight of the car as it would come off track after a race. So that's with dirver and safety stuff and remaining fuel load.

Based on that I can have a minimum power/weight ratio of 8.7 lbs/power. 3118/358 = 8.71. The heavier I run the car the more power I can run.

Now on top of all of this stuff in the TTA class I can spend modification points. In this case I can spend 19 before I'd ahve to move up to the next class which is TTS which is where I ran the Panoz. In TTS there are no modification points... it's "anything goes" so long as you stay above 8.7lbs/horse. I've spent my 19 points as follows:

1. 7pts - C5 Z06 is docked 7 pts from the start for simply being what it is.
2. 9pts - Hoosier A6 tires 13pts, however since I'm running a smaller 275 all around I get 4pts back so it's actually 9pts. Running the smaller tire also allows me 0.4 back on the hp/weight ratio. So by running them I can be at 8.3 lbs/horse which is where I get the previously mentioned 370-375 max figure.
3. 2pts - T1 swaybars
4. 1pts - ATI Superdamper UD pulley/balancer
Total = 19

So I'm done.... that's why I'm running stock manifolds and a stock air intake w/ a drop-in filter etc. Everything else done to the car is a no-points mod. Updating to the 2004 spec shocks, '02-'04 spec H-pipe, '02-'04 spec air intake, fresh springs/oil pump/timing chain, etc. etc. are all "free" mods.

The nice thing about TTA vs. TTS is it controls cost. To compete in TTS I'd need coil-overs, a bit more power, and full aero.... another $10k in the car minimum.

Hope this helps some.... if you really want to learn more about it venture over to nasaforums.com • Index page and read up on it all.

Problem I'm now facing is ride height... I have the car lowered to the max w/ the stock adjusters and it's still riding really high.

Hey when there's contingency money on the line you sort of have to have their stickers on the car :)
