Kevlar is a highly durable material that has similar engagement characteristics as organic. When segmented, Kevlar provides better heat dissipation. This material requires a 500 to 800 miles break in period.
Ceramic is a very high temperature resistant material. It's generally utilized in puck style disc for high horsepower and race applications. This material will wear flywheel surfaces faster than organic and Kevlar, especially in stop and go traffic situations.
Feramic is an extremely high temperature resistant material. It has the best friction coefficient at high temperature. The engagement is more aggressive than ceramic and is harsher on the flywheel surface. When contaminated with oil or grease, this material can fuse to the flywheel or pressure plate's riding surface. This material is only available on custom orders.
