Alright, something that's been bugging me for awhile. I had a new Centerforce Dual Friction clutch put in back in June along with a machined flywheel. Went through the entire break in process without mashing it around. When I take off in 1st gear, the car shutters, even with more gas it'll still do it a little bit. Shakes the whole car and makes an audible noise. It even does it when I'm just clutching out with no gas in my driveway until the clutch is fully released, just not as bad. Also, when I shut the car off it makes a sort of clunking noise. Could this be bad motor mounts/transmission mount/torque arm mount?
