Replace Standard Brakes with Performance Package Size?
I have a 91 z28 without the performance package. It has the stock 10.5 inch brake rotors. I was wondering if anyone has swapped the standard size rotors and calipers out for the performance package size 12 inch rotors and dual piston calipers? If so, what all needs to be replaced? Also, will the bigger rotors fit with a 15" wheel? (older z28 5 spoke wheels)

Yes the 1LE brakes will fit within the factory 15" wheels. You'll need eithe different spindles or modify your own. There are about a million threads on this. Check out the stickeys on the Brake Board first. Good luck.
