I am running RE71Rs and the car sees basically 100% autocross miles. -2.2 and 34psi are both quite a ways different than my settings - is your car competitive at autocross?

I am new to autocross, so I think a better driver would be more competitive than I've been so far. I think I'll need to re-assess tire wear when we get some warmer weather. 60-70f doesn't seem warm enough to generate any real grip with RS3's. I can't seem to get ANY heat into them with the short ~40s courses we are limited to around here. I come off course and my tires and race pads are still cold lol no fun...

I can tell you that last season at HPDE's I was seeing as high as 1.3 g's with stock suspension, 27mm front bar, M3 arms, and -1.7* camber. Front tires were scrubbing as far as the bottom of the wear triangle (still not that bad at all). same tire temps in the range of 34psi cold to 38-40psi hot.

Mods are in sig (fenders and M3 arms put me into Modified classing with the evo's )
