Aasco Lightweight Flywheel for Boxster w/ less than 500 miles, $700. It is off of my 2002 Boxster that I bought a used engine for, only to have it blow up after just a few hundred miles! My loss your gain!
I also have a Spec clutch w/ sprung disc that is matched to the Aasco Flywheel. Stage 2 clutch & pressure plate, less than 500 miles. Buy all for $1200. You'll get the whole setup for less than you can get just the Flywheel!
