You can run those A6s without studs for sure assuming you aren't running more than a 5mm shim-spacer (though I'd rather see no spacer).
315's on the front of my Z.....

Also, Brian Burdette co-drove with me this weekend at a local event. He almost raw timed Jr Johnson in his ASP vette. He liked the car, a lot. He may be co-driving my car or Lee Piccione's M3 next year in BSP.

Somehow you came up in a conversation with Brian this weekend, Chris....can't remember the circumstances.
Problem is....I am wearing the shoulders out on the stretched 285's. 60-70 runs and I am cording them. They still have plenty of life on 80% of the surface, but I can't keep the edges alive. The hope is, 315's will offer more lifespan.

I may have been vocal about it, but I didn't start that ball rolling
D.C. probably has the largest National level ESP contingent in the country....I heard it from them ALL year about the wanted jump to ESP.
In truth, once Brian got on the ****, he was of our biggest supporters for a new class. Lee Piccione also pushed hard for the new class, etc.

As you know, dynos are different. 15% drivetrain loss puts the car at approximately 298whp. Call it 17% and you're at 291whp. I think those meet expectations. In comparison, the early Z33s quoted at 287 crank were putting down ~235-240whp, or ~17% drivetrain loss as well. In contrast, our 07' Z33 showed an 18% drivetrain loss. Another 07' Z33 showed a 17% loss. The numbers I've shared are all from the same dyno.

I don't think our drive trains are that inefficient. But if they are that's more reason for consideration in class as well. I have always felt my 350z 307 hp was over stated. Guess you confirmed that for me. I haven't had it dynoed yet.
Someone finally took some pics of my car in action....
Forgot to tape up the front duct...surprised the SS (Not ****'s.....
) didn't say something. Also, need to put the rear wiper back on.




Car might be a bit too low....this is 800lb springs and under trail braking...

Is it really worth lowering the front to the point the compression rod bushing is at a self destructive angle? Necessary for tire fitment?
My springs are around 500/400 and height is around 25", heavy braking has caused slight notching on top of the UCA's where theres a pinch above it.
