I just had a repair shop install an Exedy stage 1 clutch set, struts, and alignment. Picked it up this afternoon and immediately when I started it up noticed a vibration that wasn't there before. The car revved smooth as silk before the install. at 2k rpm it feels like im driving on a rumble strip. It doesn't matter if its in gear, out, moving or stationary it still does it. Spoke to the mech about it and he thinks its because of the new trans mount I had them put in, transmitting vibrations because of it being so stiff. I'm not so sure, I believe its because something is out of balance near the flywheel and now I'm scared to death its going to shake my motor to friggin pieces. Anyone have any ideas? or did I just fork out 700 bucks to have my car destroyed??????
