My TPC supercharged 96 C4S clutch is starting to slip and I need to replace it soon.

I was thinking about putting in the lightweight clutch. Has anyone done this in the Chicagoland area? If so where did you have it done and what's a reasonable cost for parts and labor?

I was thinking about the Sachs Lightweight Flywheel & Clutch Kit at
