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.

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
*Next best to our Endurance Pads. Excellent for short races, good brake air ducts required.
Korman
High Performance 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. Not recommended for full race use.
Korman
Endurance Racing Brake Pads
Developed by BMW Motorsports specifically for endurance racing. Tested and proven on our IMSA Endurance Series M3 CSL and 328's. Nothing else comes close.
