im not sure were i can find out what BS i need for say TT2s 17x11 and 17x8.5-9.5 for a 74 camaro....i know you can fit 315/35s in the rear but i also know the BS has to be perfect....does anyone know were i can find this info?

 

Chevy hi-po magazine did an article on tire/wheel fitmanet a couple years ago. They built a test tool and check fitment for all generations of the f-body and listed spec. Maybe their website has a search function? That said, I run a 315/35 rear on a 17x11 on mine, and they only reccomended to 17x10 and a 275/40 - other than that, I don't have any 2nd gen knowledge, and this being a 3rd gen board......
