How to tell what size rotors you have
How can you tell what size rotors you have w/o removing them from the car?
I have an original 92Z w/no modifications...other than a new R-134 A/C system.
RPO codes:
FE2 Suspension Special Performance?
GU5 3.23 Ratio
G80 Positraction
G92 Performance Ratio Axle?
J65 4 Wheel Disc Brakes
A friend sent me free drilled/slotted rotors that are 11.5 inches, will those work in place of my stock rotors?
Thanks for any feed back

Re: How to tell what size rotors you have
assuming the car is still 100% stock and unmodified:
if you have aluminum 2 piston calipers in the front that are mounted to the spindle with a separate bracket, then you have 12" rotors... if you have cast iron single piston calipers that are mounted directly to the spindle, then you have 10.5" rotors.

Re: How to tell what size rotors you have
Thank you!
I even went to the local Chevy dealership's part counter yesterday, they suggested that I take the rotors off and measure them? Thanks for making it clear, I have changed the brake pads before... :-) I have 10.5" single piston
