SP Performance Cross-Drilled and Slotted Brake Rotors are a unique design providing the best combination of rotor bite, cooling and out-gassing. The holes and slots, vent gasses, improve air circulation and increase brake pad bite providing incredible stopping performance compared to stock rotors. SP Performance Sinusoidal Curved Chamfered Hole: After many years of development we have come up with a drilling and chamfering method that absolutely has no sharp edges.Our rotors are drilled with our exclusive sinusoid curved chamfer. The chamfer promotes cooling, minimizes stress, vents moisture and dust while minimizing heat checking and cracking. The smooth design also increases both rotor and pad life. Directional Curved Slots: Slots helps increase pad bite, improves air circulation and cooling. The slots also help vent gasses, reduce brake fade and stop brake hydroplaning in wet weather reducing stopping distances. Corrosion Resistant Finish: Corrosion resistant finishes give a stunning clean look behind your wheels while preventing rust, corrosion and oxidation. We Electro-Plate our rotors to provide a brighter finish which is more appealing to the look of the rotor. When Zinc plating a rotor, a metallurgical bond is formed between the plating and steel, forming an iron rich alloy with tenacious bond where it will form its own protective oxide layer. Electro- plating is very effective in combating the corrosion of the rotor. Quality: Our slotted and drilled 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.
