alot actually! im lookin at getting new rear tires next month anyway (19s dont last worth a crap) hopefully it helps out. last time at the track i peeled all through 1st and half through 2nd. this with combination humidity and temp i ran a 15.8 . it had to have been the conditions tho becausde i was still beating the ss cobalts and all the ricers. im not sure what the rsx type s are suppose to run but i they were running like 16.3s and im sure ive heard those run in the 15s high 14s. any suggestions for tires? somthing reasonably priced?
