I am looking to sell my Spec stage 3F (3+) clutch. Part number SD853F. It is rated for 475 ft-lbs and is extremely streetable. It is the best of both worlds, with almost no sacrifices. It has a full face feramic friction material on both sides of the disk. The modular flywheel is billet steel. The pressure plate is a new style and has been perfectly trouble free. I can include a flexplate with bolts if needed. I took the clutch out because I want an aluminum flywheel and don't like to mix/match.
I took it apart so you can see the friction surfaces. The surfaces are smooth, without any heat discoloration. I got the original dimensions from Spec and measured the disk to judge the amount of material left. I have used 0.0095" of the available 0.0515" from each side of the disk. Over 80% of the material is remaining. I wish I had measured this before buying the new parts, as the clutch has a lot of life left. Anyway, I paid $580 new and would like to get $200 shipped. I am open to offers.
