I just had my trans rebuilt new 26 spline imput shaft and put a new 26 spline Center Force DF Clutch in and replaced my insert on my Fidanza Aluminum Flywheel and new TB.. The problem I am having is a lot of chatter when I slowly engage clutch, i could handle a little chatter but it is vibrating the whole car and you can even hear it knocking outside the car which sucks after spending a lot to have it fixed.. I talked to Center Force and they said that clutch is an aggressive one and they don't recommend using it with a Aluminum Flywheel.. I have not heard that before and if that's the case which clutch would work with an aluminum FW or should I just get a steel one??
