I had the pucks slide off the clutch at the drag strip during a run at the track. It was a 6-puck clutch and only half of the pucks were glued on. I was picking splinters out of my mechanix gloves for weeks. I had 3 RPS clutch failures. I believe all the friction materials are glued on now, so that must have been an old clutch. I had about 420rwhp at the time.
