SP Performance Diamond Slotted Brake Rotors. This slotted design was created to maximize the out-gassing while maintaining the structural integrity of the rotor. The series of slots and diamond wipes the surface of the pad clean, and vent expanding gases which cause brake fade at higher temperatures. The slots also greatly improve wet weather braking by preventing hydroplaning between the pad and rotor. Diamond slot rotors are a unique design in slotted technology that offers styling, performance and reliability. Directional Curved Slots: Helps increase brake pad bite, improves air circulation and cooling. The slots also vent gasses, reduce brake fade and stop brake hydroplaning in wet weather, reducing stopping distances. Diamond Slots: Creates a recess to dampen expanding gasses that push against the brake pads and gives the rotors a very unique look. Corrosion Resistant Finish: Corrosion resistant finishes give a stunning clean look behind your wheels while preventing rust, corrosion and oxidation. The ZRC coating provides long-lasting protection against corrosion in the most hostile salt-water environments. After being applied, ZRC provides the highest level of galvanic protection. The film of ZRC is conductive. After the coating heats up during use, it bonds permanently to the metal surface. It will not allow the metal to corrode, even when the surface is scratched. Quality: Our rotors are made using the finest quality castings that exceed OEM specifications. Designed with the use of CAD software and produced on CNC machines insures the highest quality and consistent performance. Features: The best in quality, performance, reliability and appearance. Hassle free, bolt-on performance – No need for any modifications. The benefits of Drilling and Slotting in one great package. Increased Brake Pad Bite – Greatly Reduced Stopping Distances. Vents gases and eliminates Brake Fade Maximized air circulation for best cooling. Corrosion Resistant Coating for long-lasting protection against rust. Improved wet weather stopping. Most cost effective way of improving your vehicles braking performance. Life Time Warranty – Guaranteed not to crack for the life of the rotors. Runs cool but looks hot behind your wheels. Rotors are sold in Front or Rear Sets.
