EBC Brakes GD Sport Series Dimpled and Slotted Front Rotors for 1986-1991 Mazda RX-7 (GD538)

Fits 1986-1991 Mazda RX-7 models, including Base, Turbo, GXL, GTU, and Convertible trims, specifically for vehicles originally equipped with vented rear rotors.

EBC GD Sport rotors are engineered for high-performance street and track use, providing superior cooling and debris clearance compared to standard solid discs. These rotors are manufactured from high-quality G3000 spec grey cast iron to ensure durability and thermal stability. The wide-aperture slots pull cool air under the brake pad surface while drawing out dust, dirt, and gases to maintain a consistent contact patch. Blind-drilled dimples provide additional degassing without the crack-prone risks associated with fully through-drilled rotors.

Each rotor is tested for grain structure, tensile strength, and hardness, followed by a 100% runout inspection to ensure perfect balance and performance out of the box. These rotors are finished with a gold anodized coating to provide corrosion resistance and a distinct look behind the wheels.
