EBC GD Sport Series Slotted and Dimpled Vented Rear Rotors for 1986-1989 Mazda RX-7 (1.3L) - GD434

Fits 1986-1989 Mazda RX-7 models (1.3L Rotary) equipped with vented rear rotors. These EBC GD Sport series rotors are engineered to provide superior cooling and debris clearance for high-performance street and track-day use.

Constructed from high-quality G3000 spec grey cast iron, these rotors feature wide-aperture slots that draw cool air into the braking zone while effectively removing dust, dirt, and gases. Unlike traditional through-drilled rotors that are prone to stress cracking, the GD series utilizes blind-drilled dimples that offer the degassing benefits of a drilled rotor without compromising structural integrity. Each rotor is finished with a gold anodized coating to provide long-lasting corrosion resistance and a premium look behind your wheels.

• Replaces factory vented rear rotors with upgraded slotted and dimpled performance units
• Wide slots reduce brake temperatures and help prevent brake fade under load
• Blind-drilled dimples maintain rotor strength while facilitating pad degassing
• Gold anodized finish protects against rust in salt-heavy or humid environments
