New clutch setup won't disengage

hmm... I have a Centerforce DF disc & pressure plate, which does have a ring of weights on the fingers. How far do those fingers deflect?

On the other hand, I don't ride the pedal and the car will only see high rpm in short bursts...

It depends on the lever and I don't use either diaphram or center force stuff. The lever won't always move due to CF but it's something to think about.
