From what kind of material is the clutch shoe?

If I am not mistaken, the clutch material is Nylon plastic. But you also have some aluminum clutch shoes, and some carbon shoes. What clutch material are you asking about?

PTFE or in a normal name Teflon.

It comes in several colors and mostly the color is telling the substansion.

A thanks, just read here:

That they use filled PTFE, thus with other materials to change mechanical properties.

There have been some other materials used. For instance, I believe the old Delta Reds were some sort of floor tile or something. Great shoe.

I have seen them as well, from Ferodo but I think it is to expensive.

The red Teflon cost about 80 euro a bar of one meter, with that you can cut 100 shoes. Calculate your profit if you sell them for the Mugen price

Work in progress....imagine all parts..

The Mugen was the Delta. Saw Dave hand them a bag full of them once.
