We installed a new Exedy Mach400 clutch recently. It works great, except sometimes during a rapid upshift 1-2 it will grind (during autoslaloms).

We put the original clutch cable in the car, would an adjustable cable/quadrant help this issue?

 

Hey, Did you replace or resurface the flywheel. Is there any drag from high points on the fly wheel. Just a thought.
