I went to order a rear brake caliper for my rx7 from autozone and the guy said does it have normal or hard suspension. I told him normal but i have no clue, how do you tell if it has normal or hard?????

 

rear brakes on the normal suspension listing will be solid disk, while heavy duty will be vented.

And easy way to check is to see if you have 4 piston front brakes. If you have a single piston you have the normal suspension, if you have 4 piston front brakes you have heavy duty suspension.

As a note: there is really no such thing as heavy duty or normal suspension on the S5 models, but the autozone parts books don't know that and they list the brakes based on the S4 nomeclature.

 

I have 4 piston front calipers, i told the guy normal suspension, Is there only one caliper for the rear even though they list two or will i be getting the wrong caliper????

 

No, if you have 4 piston front brakes and vented rear rotors, the rear caliper for a Standard suspension vehicle will not fit (too narrow around the rotor).
