I still have this thing laying around my shop. Belongs to a customer of mine who has no need for it. Brand new is over $2000. It was used barely used. Exedy did a inspection and the thickness is 4.3mm. New is 4.6mm. Replacement thickness is 3.6mm. This clutch is perfect for NA 350z/G35. It was switched out by recommendation due to turbo installation. Not a recommended clutch when pushing over 400wheel. Current asking price is $800obo.
