R53 clutch help
 

Last December the stock clutch on my R53 S finally gave out after 120K miles. I had it replaced with a SPEC lightweight flywheel and Stage 2 clutch kit. 21K miles later it is slipping when cold and the pedal take-up point is all the way at the top. My shop is tearing it down today for a visual confirmation. My question is: what clutch do you guys recommend to use with the flywheel? I need something that will last more than a year. The car has the a few bolt-on mods, but is never on a track: cold air intake, 15% reduction pulley, cat-back exhaust, and upgraded plugs and coil pack. (It's my son's car, I don't remember all the details.)
