I made a post a couple days ago regarding my brand new Clutchmasters Stage 3 Clutch and Fidanza 7.5lb flywheel... It was about my clutch pedal being soft, buu I have a much more serious problem...

When I am taking off from a dead stop, unless I rev up to about 3000rpm, the car chatters like crazy... For example... If I was taking off like normal, the car would start to chatter (or shake) until I hit about 2500 rpm then it would be smooth...

All the other gears are smooth it's only taking off that is a problem...

If anyone could help me with what this is because at stop lights I'm either chattering like crazy or I'm peeling out...

Maybe the flywheel is not lined up right against the clutch?? Help PLEASE!
