1987 GT doing the brakes and rotors all front and back. After going on the fiero store website they sell just the one basically stock rotor for 84-88. Are all the rotors the same size? So all I'd have to do is enter the quantity as 4 and I'd be good to go? Thank you!
No. The front rotors on the '84-'87 cars are different from the rear rotors on the '84-'87 cars, and the '88's use rotors that are different front to rear which are different from the earlier cars as well. None of them are interchangeable with the others.
