All those dual friction, ceramic and whatever gimmick they use to make the clutch not slip.
There are two cutch discs to use. An organic disc (both sides) with 2400-2800 pounds of plate pressure at the most.
Or you use the sintered iron disc and keep the plate load between 800-1500 pounds, maybe a bit less if the car is light.
The rest of that **** is just that. ****.
A clutch is NOT a toggle switch. But that’s what they are when you use the gimmicks. And that breaks parts.
