I purchased this clutch due to the fact of the price of about $150 shipped. I willing to use this clutch to it fails. The TOB is made by NTN bearings(pretty good brand). The clutch disk itself is Rabesto material, it had its label on the clutch material. The sprung center section seems to be of good quality, and its made in the USA. It also looks alot better than an OEM replacment. The alignment tool worked like it should. There is a 500 miles breakin period with this clutch. I have about 2000 miles on this clutch and no problems on launches around 4k and heavy driving. I Rebuilt my engine at 1000 miles and i check the condition of the clutch, it looked good. Will try to keep this updated. EBAY seller is GRIPFORCE if you wanted to know.
