Alright guys, I've recently added a cam and a 10" ptc converter to my car. I'm running nittos on the stock wheels and they are not cutting it. Last trip to the track my reaction times are almost perfect on pro tree. .005, and .004. Sixty foot times of 2.4...... And I've got some serious wheel spin. I'm looking to go with a tire with a taller side wall to help hook it. Anyone running 15s and know the back spacing. All help would be greatly appreciated. Thanks!
