Just a question are 88 and 90 and up to 96 rotors interchangeable????

 

Check back to last year's threads on rotors, there is 12'and 13' diameter.The larger rotor is heavy-duty. Very likely interchangable as long as the dia. is the same.

 

I believe they are,maybe it was just a difference in suspension options,like standard,Z-51 or Z-52.My '96 originally came with the smaller "12 rotors,but changing them to Bear "13 Decelarotorswith the Grand Sport calipers was no problem at all...and of course my car stops a lot better.
