Important Note: These rotors are specifically designed for use with our custom Wilwood 4 Piston Big Brake Kit. Please do not place an order for these rotors if you are not going to use them for their intended design.
Machined And Finished In Our USA Facility
All Performance Slotted Brake Rotors are precision-machined and finished in our U.S. facility. Every rotor is inspected using the strictest quality control standards and checked for compliance with factory dimensional specifications. Our rotors are manufactured from premium-quality cast iron that meets or exceeds G3500/ISO9002,QS9000/VDA 6.1 specifications. Each rotor is double-disc ground and machine-mill balanced for optimal high-performance operation. We are so confident about the quality of our products that we offer the best warranty anywhere!
Performance Full Curve Slot Design
Each Performance Full Curve Slot is strategically machined off the edge of the rotor to dramatically improve braking performance by up to 30% over factory stock brake rotors. Our slot design removes water, dust, and debris whilst minimizing the heating of the pad surface. Slots that are machined in the center of the pad surface are inefficient and only collect dust. The edges of our slots are machine-rounded to achieve maximum degassing and dust removal.
Zinc Plating In Black or Silver
Our Performance Rotors are Zinc coated in Black or Silver. The Zinc Coating Process is an extensive hand-applied operation that is not sprayed on like inferior coatings. Each Performance Brake Rotor is immersed in different solution tanks throughout the coating process. The final result is a thick protective coating that will help prevent rusting and give you a great custom look.
