Tenaci 240 mm organic sprung clutch disc 26/35 BMW 26 splines 35 mm shaft

This clutch disc have a really long lifetime.
Capable of high loads without burning or exploding.
When pushed beyond the torque limit these springs will not bottom but rather get worn with time instead which means you can just replace the springs when they’re weak.

One way of prolonging the life of the disc is by changing gear distinctively, releasing the clutch pedal quickly to avoid clutch slipping.
Avoiding clutch dumping on high gears also helps prolong the life the clutch.
