i am thinking maybe as they wear they get lighter and so engage earlier possibly bogging the motor out of corners??
should i try running 1.1 springs with the carbon shoes or try some alloy ones?
Hi TB, Put a set of alloy's with 1.1's on your 3 port, you will love it. That is what Paul runs on his 3 Port and it hauls. Stock 5 Port, for our track conditions try 2 x alloys with 1.1 springs and 1 x carbon with a 1.0 spring. spring. If that'a a bit too much, go for 2 x 1.0 springs and 1 x 1.1 spring with all alloys.
As the shoes get lighter they will engage a little later, not earlier. Less mass for the centrifugal force to act on, so they won't move until the clutch is spinning faster.
I always run alloys and the clutch bells seem to take it OK. I give the bell a quick spruce up inside with a bit of fine emery paper each time I take the bell off for any reason. This seems to keep the inside surface pretty smooth and groove free.
