I remotely considered installing my Exedy clutch last year...did some research on how to do it. I own a Hayes, looked through that. DON'T DO IT! I'm assuming that you're pretty coordinated and good around tools...but honestly, a clutch is not something easy to do. Think about it, it's one of the most important parts of your car. The A/C, Radio, Stereo, Alternator, Battery...etc...ALL DIY. But just like you wouldn't do any massive stuff on the engine. I'd think twice, 3~4 times before trying something with your transmission. The best price my mechanic gave me was $280 to install my clutch and change my oil (negligible cost).

Anyway, Yea it would hella be nice to be able to do it yourself, but seriously, your clutch is everything.
