Havne't heard of that one. Description kinda sounds like it is metallic on one side and organic friction material on the other side of the disc....it it is you don't want it. Organic friction material is the way to go for most use, metallic eats up the flywheel and/or pressure plate depending on the clutch disc if it is metallic one or both sides.

Luk is good quality clutch set.
