The following quote is from an email I received from MM about LFW:
Hi Chris,
The lightened flywheel for your car is a great performance modification. Unfortunately the flywheel in your car is a dual mass flywheel, which can not be lightened. What we sell is a E30 325is flywheel. This flywheel weighs about 20-23 lbs from the factory. Our lightened flywheel weighs about 10-12 lbs. With our flywheel you also need a clutch & pressure plate kit to go along with the flywheel. This setup is a perfect plug and play kit with no other modification needed. In the end you will get rid of the dual mass 28 lb flywheel for a lightened single mass flywheel. The kit sells for $700 and includes the flywheel, a 228mm clutch disc, 325 pressure plate & release bearing. We would need your ring gear from your flywheel or if you don't want your car down that long, we could send you the flywheel first and charge you a $100 core deposit until we receive your ring gear from you, at which time we refund your core deposit (assuming it is a useable core). If we can help you, give us a call at 573-765-1269.
Thanks!
Regards,
Court
