I am about to change out my clutch/pressure plate/ throw out and pilot bearing and I didn't get a new flywheel with the kit. I was told that I could have my stock flywheel resurfaced however when I called the machine shop to get a price quote he told me that if I didn't get a pressure plate and flywheel together that was matched and balanced that a new clutch wouldn't work without a horrible vibration. I felt like he was trying to sell me something but i thought I would check with you guys on here first. Anyone know of this horrible vibration he speaks of? I would just send my clutch kit back and get a new one with a flywheel but I'm leaving California in 2 weeks to go back to the east coast where i'm stationed and i just don't have the time. any advice would be great. The clutch I bought is a SPEC Stage 2.
