That is a black magic clutch disc. A lot of higher HP vw guys use that disc with a stage 1 plate.
I love this disc!!! Used to drag with, and can be freshened up by media blasting after a few runs. Almost like new. A little harsh on take off, but locks right up. Less harsh I found if hydralic clutch is used. also check out the Gene Berg dual friction disc.
