Ok I have a 90 GTU and a 88 GXL. I wanting to take my Centerforce DF clutch out of my 90 model and put it in my 88 model. But I noticed that they carry 2 different clutch for the NA, one for the S4 and one for the S5. Whats the difference between the two? Is there a way I can still swap them? Different Flywheels? I know the transmissions will mount to either one sincei have a S4 tranny right now in my S5.

 

Different clutch disc thickness - it should swap over.
