Just like flywheel weight, the weight of the clutch pads and disks adds up.Originally Posted by kuhlka
I will get Matt at Spec clutches to explain this better than I can. But, the composite used in the pad material differs based on pressure developed and temperatures seen. The material used in the clutch plate changes the flex and the heat dissipation as well.
Sintered - is sintered iron, carbon is a composite that can be full or partly carbon - light but some designs flex a lot more than others, and aluminum is best for heat dissipation, but flexes more than iron or steel when hot.
Pad/puck shape and surface area is as big of a deal as pad and plate material.
