EBC S4KF1609 S4 Kits Redstuff & USR Slotted Rotor Brake Kit

The EBC S4KF1609 is a complete Stage 4 brake upgrade kit pairing EBC's high-performance Redstuff Ceramic Sport Brake Pads with USR Fine-Slotted Sport Rotors — everything needed for a premium front or rear brake upgrade in a single, value-packed bundle.

Redstuff Ceramic Brake Pads:

• Formulated with Aramid fiber enhanced with ceramic granules for superior braking performance and reduced brake dust
• Fully shimmed, slotted, and chamfered for quiet, vibration-free operation
• Features EBC's patented Brake-In coating for rapid pad seating after installation — no lengthy bedding-in process required
• Delivers strong, confident braking power with zero brake fade
• Ideal for muscle cars, premium imports, and performance-oriented daily drivers

USR Fine-Slotted Sport Rotors:

• Fine-slot design sweeps debris and gases away from the pad surface for consistent, silent braking
• Vented construction promotes heat dissipation for cooler running brakes
• Guaranteed flat and parallel — ensuring even pad wear and long rotor life
• Thermic Black anti-rust coating provides long-lasting corrosion resistance; coating is safely removed by the brake pads within the first 10–20 stops after installation
• Do not remove the Thermic Black coating with brake cleaner or abrasives — doing so voids the EBC warranty

Kit Includes:

• EBC Redstuff ceramic brake pad set
• EBC USR slotted sport rotors (2-wheel set)
• Caliper lubricant

Buying this kit saves money compared to purchasing pads and rotors separately. Do not fit upgraded pads to the rear of a vehicle unless the same upgrade has been fitted to the front. EBC brake pads and rotors are manufactured in EBC's own facilities in the UK and USA.
