Hello!

You are an engineer, right?

Puck-type disc will usually not hold for more torque. Actually, it's pucks usually have less mu, less friction than organic stuff on ordinary clutch. Only difference is that they will hold for more heat w/o going up in smoke (chewing away your flywheel in the progress).

W/o words, you could remove organic material from your ordinary disc and install pucks. The less pucks you have the greater pressure per square inch you get, but the less surface also.

With other words, only thing pucs do is to raise contact pressure per square inch, but total friction stays the same due to less surface.

Only reliable way of increasing the torque specs is fitting stronger pressure plate. In case you don't do track-only, I recomend keeping the stockish disc and increasing the pressure plate force. It will still give somewhat normal slipping characteristics opposed to pucked disc and hold for torque.

Then there is a issue of aftermaket puck-discs usually not having dampening springs in the middle. Tose springs are there to even out power-pulses going into the gearbox. Not having them increases wear and tear as inpuut shaft will be banged by micro-bursts.

So all in all, stay clear of undamped pucks unless you emptied other solutions: stronger pressure plate is the first to try.
