EBC Brakes 3GD Series Slotted & Dimpled Rear Rotors GD639 - Select Ford, Mazda, and Mercury 1990-2005

Fits select 1990-2005 Ford Escort, Mazda Miata, MX-3, Protege, and Mercury Tracer. These EBC Brakes 3GD Series rear rotors are engineered to solve the common issues of brake fade and surface glazing. Precision-cast from high-quality grey iron, these rotors feature a wide-aperture slotted and dimpled design that actively draws cool air into the braking zone to reduce operating temperatures by up to 200 degrees.

The dimpled holes ensure the structural integrity of the rotor is maintained compared to through-drilled designs, while the slots clear dirt, dust, and gases from the pad contact area. Finished with a gold anodized coating for corrosion resistance, these GD639 rotors are ideal for high-performance sedans and sport coupes requiring improved heat dissipation under load.
