I'm getting ready to change my clutch out (94 325iS), and I have a couple questions. 1. for a stock clutch, is $500 a good price for parts and labor? 2. are there other options when doing a chutch, ie: is the M3 clutch different/better? 3. what is the best and second best clutch to use? 4. is it really worth it to do the LTW flywheel when doing the other stuff, and where is the best place/price to get it?
