It has been asked by many Moparts members what size tires and wheels that I am running with the Alterkation and street lynx suspension. After careful measuring ,the front wheels are 17X8s and a 5.72 back space ,with 245 45 17 Nitto tire . I am running a 1/4 spacer betwwen the wilwood rotor and the wheel on the front. The rears are 18X10 rims with a 7.24 backspace the tires are 285 40 18 Nittos. Overall you want to shoot for 27 diam and 11 with in the back. I have plenty of room to lower the car another 1" to 2 " in the back without modifying the wheel tubs. Those are mustang Bullet wheels bought directly off the American Muscle website.
