EBC S4KR1392 S4 Redstuff Ceramic Brake Pad and USR Slotted Rotor Kit

The EBC S4KR1392 S4 Kit pairs EBC's high-performance Redstuff ceramic brake pads with USR fine-slotted sport rotors into a complete 2-wheel brake upgrade kit — delivering measurably shorter stopping distances, significantly reduced brake dust, and near-silent braking for muscle cars and premium imports.

EBC Redstuff Ceramic Brake Pads:

• Aramid fiber compound enhanced with ceramic granules for high braking efficiency with minimal dust
• Fully shimmed, slotted, and chamfered for ultra-quiet operation
• Features EBC's patented Brake-In coating for rapid pad seating immediately after installation
• Zero brake fade performance across a wide speed range
• FMSI Pad No. D1562

EBC USR Sport Slotted Rotors:

• Fine-slotted vented rotor design expels heat, water, brake dust, and friction gases for cooler braking
• Dual slot pattern promotes flat and parallel pad wear — preventing ridges and uneven wear across the rotor surface
• Vented center construction allows air to circulate between rotor faces, minimizing thermal expansion and warpage risk
• Finished with Geomet black anti-rust coating for long-lasting corrosion resistance on non-contact surfaces
• Specifications: 350mm diameter, 19mm thick, 35mm height, 71mm center hole, 5-bolt pattern, vented

Kit Includes:

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

Warranty: Covered by EBC's 12-month / 10,000-mile limited warranty against defects in materials and workmanship. Warranty excludes race, track, taxi, or competition use.

Installation Note: Do not fit performance upgrade pads to the rear axle only — always match the same upgrade level front and rear. The Geomet anti-rust rotor coating does not need to be removed before installation; it will self-clear in the pad-swept area within the first 10–20 brake applications.
