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.

My 88 has the same rotors on all 4 wheels. For that matter, so does my 86, but they're not stock -- they're Grand Am rotors.

The Fiero Store titles group the parts together. Check the drop-down menus under the titles to select the years.

Thanks everyone for the replies!
