High-Performance Braking with EBC S4 Kits

Upgrade your Subaru’s stopping power with the EBC S4 Kit, combining the high-friction Redstuff ceramic brake pads with precision-engineered USR slotted rotors. This kit is designed for drivers who demand superior performance, reduced brake fade, and significantly less brake dust compared to OEM components. By bundling these premium parts, you save 15% over purchasing them individually.

Kit Features and Benefits:

  • Redstuff Ceramic Pads: Aramid fiber enhanced with ceramic granules for high-speed stopping power and low dust.
  • USR Slotted Rotors: Fine-slotted design for silent, cool braking and flat, parallel pad wear.
  • Geomet Coating: Advanced anti-rust finish to keep your rotors looking sharp.
  • Brake-in Coating: Patented surface coating for fast pad seating immediately after installation.

This kit is specifically engineered for a wide range of Subaru models, including the Impreza 2.5 GT, WRX, and the high-performance WRX STI. Whether you are navigating city traffic or pushing your car on a mountain pass, the EBC S4 kit delivers consistent pedal feel and reliable performance. The slotted design helps evacuate gases and debris, ensuring the pad surface stays clean for maximum bite. All components are fully shimmed and chamfered to prevent noise and vibration. Trust your stopping power to the experts at GGCRACING.
