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.
Korman
High Performance Brake Pads
A superior carbon-kevlar material that far exceeds the capabilities of usual street performance pads. For road, rally, autocross and track use. Wide friction coefficient make them work well hot or cool. Rotor friendly.
