Alright so my new GT has cobra brakes all the way around. I already know the story with the front's. Pretty much a 15" wheel aint going to fit unless I run a spacer. Understood. I am more worried about the rear. I have the factory GT rear with the cobra 11.XX" brakes. I have some people tell me that 15"x8" welds with 5.5" backspace or 15"x10" with 6.5" backspace will work and some say wont work because I have a solid rear. I cant afford to buy a set of wheels and find out they dont fit, and I am not grinding or cutting or anything. Now, I found someone with some 16" Weld Draglite XP's that I am 75% sure will fit, but I would rather have Pro Stars, but can deal with Draglite's because its just for track use. I also found some pro star xp's but in 15x9". Anyone have an awnser. I am going crazy trying to figure what will and wont fit.
