haha no i got the same flywheel a while back for 60$. I don't have the car running yet but I did run in to one problem. The recess for the flywheel bolts was too high and the stock clutch springs hit the flywheel bolts. So, I had to sand down the recess a bit and also grinded my arp flywheel bolts down a bit. This was with a stock clutch though, I believe performance clutches have a smaller diamater spring. The flywheel other than that looked great, but I have yet to run the car. I'll let you know how it is, cuz hopefully it'll be up and running soon.
