Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are specifically designed for the Mazda RX-8, providing a balance of durability and performance. The vented rotor construction with straight vanes promotes efficient heat dissipation, reducing the risk of brake fade during aggressive driving or track use. The cross-drilled and slotted surface pattern helps evacuate gases, dust, and water from the braking surface, improving pad bite and overall braking consistency.

These rotors have a coated hat finish that protects against corrosion, extending the rotor's service life. The floating disc mounting design allows for slight movement between the rotor and hub, which can help reduce stress and improve rotor longevity. With a center hole diameter of 71.8 mm (2.827 inches) and a mounting bolt hole circle diameter of 114.3 mm (4.5 inches), these rotors are engineered to fit precisely on the Mazda RX-8's 5-lug wheel hubs.
