what does a 911 primary cover do for you? any performance gains? bolt on with no adjustments?
It uses a large bushing that the moveable shive slides against. It is supposed to give smoother shifting & better primary clutch performance. I have one on my RX-1 cus i got it cheap but can,t tell if it is doing anything.

It makes everything last longer. Rollers, pins and weights all seam to last twice the mileage as with the stock cover. A good investment. Bill
