Features: WAVE® design allows for lower operating temperatures at extreme conditions. Each rotor is individually heat-treated and double-disc parallel ground to ensure perfect flatness. Laser cut, never stamped. Much lighter than a stock rotor. Features Cryo-Tech® treatment which cryogenically transforms the steel to a significantly harder and more stable phase, resulting in improved durability, wear resistance, and long-term performance. Brake Rotor Fixed Wave 190.
