is it possible that my flywheel is bad if i have a vibration that starts out small but increases just sitting still and revving up the motor? ive replaced everything but the clutch and flywheel setup. no problems with the clutch but i can't think of anything else that it could be. this is on a modified 95 gts. it puts down 325 to the wheels. everything from the harmonic damper to the alumn drives shaft. it is very minimal now but it will throw a cel above 4500 rpm. then it really is noticeable .maybe go with an aluminum flywheel?it has a cobra clutch in it now.any ideas?
