Korman High Performance Brake Rotors

Available in either a computer controlled crossdrilled version with the holes chamfered to the wear limit, or in a computer controlled gas slotted version with the gas ports milled to the wear limit. Our rotors are then finish plated with cadmium. While nothing beats the appearance of crossdrilled rotors, we suggest using the gas slotted versions for true high performance and track use due to superior wear rates and brake cooling. Please specify crossdrilled or gas slotted when ordering.

High Performance Brake Pads

Ferodo Performance Brake Pads

Developed as a non-asbestos street alternative. Formulated with metallic fibers and other inorganic substances that yield a high friction level with good resistance to fade and wear. This competition grade compound is completely suitable for normal street use as the friction level is affected very little by temperature.

Hawk High Performance Disc Brake Pads

Korman Endurance Brake Pads

In our development of the 325 for IMSA Endurance Racing, we tested every brand name racing brake pad we could buy and then had some custom fabricated as nothing "off the shelf" would last. We finally found a custom material that was good enough to win the 24 Hours of Watkins Glen and both the Driver and Manufacturers IMSA Sport Class Endurance Championships. An added bonus is that they stop well under light street conditions, making them completely suitable for street/highway use as well as driving schools and Club Races. Sold on an exchange basis (we need your old backing plates back as cores)

Korman Racing Brake Pads

Developed for use in our IMSA E30 M3's. Good enough to win both the drivers and the manufacturers IMSA Sport Class Endurance Championships. This pad material is a non-asbestos graphite/metallic formulation. Unlike some racing materials that work well only when hot, the broad coefficient of friction of these pads also enable them to work well under cool, light braking conditions. They are therefore ideal dual purpose pads for both street and club events.
