Product Description

The EBC S5KR1378 Stage 5 Rear Brake Kit pairs high-friction Yellowstuff brake pads with GD Series slotted and dimpled rotors to offer a substantial upgrade over many stock rear brake components on the 1993-1995 Mazda RX-7 with the 1.3 L rotary engine. Designed as a direct bolt-on solution for rear braking, this kit enhances initial brake bite, overall modulation, and heat management - helping to deliver more confident and consistent stopping performance during daily driving and spirited street use. GG-rated Yellowstuff pads are engineered to provide stronger friction levels than many OEM compounds, improving rear braking feel without brake system modifications.

GD Series vented rotors feature wide slots and dimples that promote efficient heat dissipation and help evacuate gases, dust, and debris from the pad surface - which helps maintain consistent pad contact under load. The corrosion-resistant Geomet/thermic coating on the rotors improves longevity against rust and environmental wear. With straightforward installation and robust performance enhancements, the S5KR1378 kit is ideal for RX-7 owners seeking a reliable rear brake upgrade that fits factory hardware and enhances brake response.
