I am finally putting a few miles on my car with the Tremec. I have pretty bad clutch chatter in first gear and some slipping in the other gears. I have the standard clutch set up with the fork. What should I adjust to help with these things?

You can't adjust chatter, something is wrong. Are the flywheel, PP, clutch, trans, fork all new?

Everything is new parts.

Who did you puy your Kit from ??? if its all new did you clean your flywheel and pressure plate REAL GOOD I had to use a whole can of brake clean to get the shipping cosmoline off both surfaces it was soaked into the pores of the steel ..My experience with chatter,yrs ago was an out of balance or poorly adjusted pressure plate, oil on the flywheel, pressure plate or disc , glazed disc, all the conditions I have above just shook the whole car when engaging the clutch, Sorry Luke ,I am sure you can't adjust out chatter…Happy Motoring soon I hope
