This is a stock 200mm clutch kit using the Exedy -581 plate. Good for 1600's and marginally acceptable for 2L. Good for taking the kids for ice cream, but not heavy duty!
A complete clutch assembly plate, bearing disc, pilot bushing.
This is the same identical 510 clutch that Datsunparts.scam attempts to market as a roadster clutch. It isn't, but it will bolt up and be functional.
Upgrading to the 225mm is reccomended and better in every way if you want both fantastic performance and excellent longevity. Who likes pulling engines?
