clutch thickness


I have a turbo build with brocks clutch mod and using an NLR boost compestaing clutch. Can I run normal OEM fibers and steels at 2in thickness? When I pulled the clutches out they are thicker than 2in, has extra fiber and steel.

I have never messed with clutches. What is the difference between running a thicker stack vs a shorter stack? I would assume a thicker stack would mean more pressure on the plates and less slippage when on the throttle.
