EBC S4KF1940 S4 Kits Redstuff and USR Rotor Disc Brake Kit

The EBC Brakes S4KF1940 S4 Kits combine high-performance Redstuff brake pads with premium USR (Ultimax Slotted Rotor) rotors for a complete front and rear brake upgrade. This kit delivers enhanced stopping power and fade resistance compared to standard braking components, making it ideal for spirited street driving and light performance use.

Key Features:

• Redstuff ceramic brake pads feature EBC's patented Brake-In coating for faster bedding and immediate performance
• USR rotors are precision-machined with directional slots to reduce brake dust and improve pad bite
• Premium thermic anti-rust coating on rotors protects against corrosion and ensures long-lasting appearance
• All rotors are fully balanced and run-out tested to eliminate vibration and ensure smooth, consistent braking
• Low dust ceramic formulation keeps wheels cleaner than traditional semi-metallic pads
• Complete kit includes everything needed for installation—pads and rotors for specified axles

The S4 Kits Redstuff series is designed for drivers who want improved braking performance without the noise and dust associated with aggressive track pads. The Redstuff compound offers excellent cold bite and progressive pedal feel, while the slotted rotors help maintain consistent temperatures during demanding driving conditions.
