Would the car be quicker if you could stuff those 355s under the rear? I think with the right rims I could go about another 2" on the rear at least.

Those 25 ratio tires have very short sidewalls. Must work ok. Cannot argue with your results!

To be honest with you I don't know, we beat the Summit boys by 1 second when they were on Rivals and we were on Bridgestone's and both of us had big rears. We beat them by 1 second when they had big rear Kuhmo's and we had small rear Kuhmo's so it is hard to project. What we lose on the launch we gain back in corner speed. Applies to small tight courses only 355's would be better on high speed stuff.
