These brackets allow the use of 88-95 C4 12" rotors and 88 Fiero calipers on your 84-87 fiero. You will need 16" wheels at the min but I have heard of people getting the stock 15" wheel over them on 88's. People have been doing this swap on 88's for years, it is very well balanced, lightweight and affordable. Using the 88 Fiero caliper allows you to have an e-brake, nothing needs to be done to the cables or the calipers. The fronts are a bolt on and will require a hub made to install the new rotor onto. I have these available here-//www.fiero.nl/forum/Forum4/HTML/071647.html When you install the rear calipers you will need to swap sides, Driverside on the pass side and pass side on the driverside. This will put the bleeder facing down requiring you to bleed the calipers off the car, I have done it several times and it isn't hard to do. Also the Threaded holes that hold the bracket to the knuckle will need to be drilled out and tapped with a M12x1.75 tap, I will include the required drill bit and Tap with each set of brackets.
