EBC S20K1111 Stage 20 Ultimax Brake Pad and RK Rotor Kit Front and Rear

The EBC S20K1111 is a complete Stage 20 two-axle brake kit that bundles Ultimax brake pads and RK Series OEM-replacement rotors for both the front and rear axles into a single, value-packed package — along with caliper lubricant. Replacing all four corners at once ensures balanced, even braking performance, since rear brakes contribute up to 40% of total stopping power.

Ultimax Brake Pads:

• Constructed with aramid fiber (low-metallic compound) to reduce rotor wear while maintaining strong braking efficiency
• Fully shimmed and chamfered to minimize brake noise, vibration, and judder
• Feature EBC's patented Brake-In™ red top coating that scours away glaze and heat spots from the rotor surface for faster, more even pad seating right after installation
• Designed to match OEM dimensions with tight tolerances for proper fit and consistent wear

RK Series Rotors:

• Direct-fit OEM replacement — no modifications required for installation
• Coated with Geomet anti-rust surface treatment to protect against road salt, brine, and corrosion
• Cast from high-carbon gray iron to reduce brake shudder, heat cracking, and high-frequency vibrations that cause squealing
• Vented center design promotes airflow between rotor faces for more effective heat dissipation and reduced pad fade
• Fully balanced and runout-tested at the factory for smooth, vibration-free braking right out of the box

What's Included:

• Front and rear Ultimax brake pads (complete set)
• Front and rear RK Series replacement rotors (complete set)
• Caliper lubricant

The EBC S20 kit is ideal for everyday street driving, truck and SUV use, and light performance applications. Renewing all four corners simultaneously maximizes braking balance and helps extend the life of the entire brake system.
