Actually fiero addiction is not producing the kit if I remember right. Bmwguru on pennocks is making brackets so the 84-87 cars can use the 88 calipers with the vette rotors.... that's the way u want to go. I was going to do it but I have too much $ in the stock set up. I was hoping for someone else to pull off a solid rotor in a larger diameter like fieroguru started but abandoned. Or of I could find a set of cheap to free 88 calipers. I just don't have the $ to replace everything.
