Product Details

The EBC Brakes S4KF1773 S4 Kit combines high-performance Redstuff brake pads with premium USR slotted rotors to deliver a complete brake upgrade solution. This kit offers a cost-effective alternative to purchasing components separately while ensuring optimal compatibility between pads and rotors.

Key Features:

  • Redstuff ceramic brake pads with EBC's patented Brake-In surface coating for faster bedding and immediate performance
  • USR (Ultimax Sport Rotor) slotted rotors with precision-machined slots to reduce pad temperatures and improve bite
  • Thermic black anti-rust coating on non-friction rotor surfaces for long-lasting corrosion protection
  • Each rotor is fully balanced and run-out tested to eliminate vibration and ensure smooth, quiet braking
  • Low-dust Redstuff compound keeps wheels cleaner while delivering strong stopping power
  • Ideal for spirited street driving and light performance use

The S4 Kit provides an excellent balance of performance, longevity, and value for drivers seeking an upgrade over stock braking components. The Redstuff pads are engineered to work seamlessly with the USR rotors, maximizing pad life while reducing brake fade under demanding conditions.
