EBC S20K1667 Stage 20 Ultimax Brake Pad and RK Rotor Kit Front and Rear

The EBC S20K1667 Stage 20 Brake Kit is a complete two-axle brake solution that bundles everything needed to refresh both front and rear braking systems in a single, value-packed package. The kit includes Ultimax brake pads for both axles, matched RK replacement rotors, and caliper lubricant — delivering a cohesive, balanced upgrade over piecemeal part purchases.

Ultimax Brake Pads:

• Engineered with a blend of synthetic aramid fibers and metallic filament for long-lasting, high-friction performance
• Fully shimmed and chamfered to minimize brake noise and vibration
• Pre-applied EBC Brake-In™ coating accelerates pad seating on rotors right out of the box, reducing the break-in period
• Centerline slot design helps channel heat and gas away from the pad surface
• Designed as a premium OEM-quality replacement for everyday street and urban driving

RK Series Replacement Rotors:

• Direct-fit OEM replacement — no modifications required for installation
• Protected by a GEOMET anti-rust surface coating that guards against road salt, brine, and corrosion
• Manufactured from high-carbon gray iron to reduce brake shudder, heat cracking, and high-frequency vibration
• Fully balanced and runout tested at the factory for smooth, judder-free braking performance
• Vented rotor design promotes airflow for effective heat dissipation and reduced brake fade

Why Replace Front and Rear Together?

Rear brakes are responsible for up to 40% of a vehicle's total stopping power. Replacing only the front brakes leaves worn rear components limiting overall braking efficiency. Refreshing both axles simultaneously with the S20K1667 kit ensures balanced, maximum braking performance and helps extend the life of the entire brake system.

What's Included:

• Front Ultimax brake pads (1 set)
• Rear Ultimax brake pads (1 set)
• Front RK replacement rotors (pair)
• Rear RK replacement rotors (pair)
• Caliper lubricant
