EBC S20K1143 Stage 20 Ultimax Brake Pad and RK Rotor Kit Front and Rear

The EBC S20K1143 Stage 20 Brake Kit is a complete front and rear disc brake solution, bundling Ultimax brake pads and RK plain rotors for both axles into a single, value-packed kit. Designed as a direct OEM replacement upgrade, this two-axle kit includes everything needed to refresh your entire braking system in one installation.

Ultimax Brake Pads:

• Constructed with Aramid fiber reinforcement for high efficiency and durability
• Fully shimmed and chamfered to minimize brake noise and vibration
• Features EBC's patented Brake-In coating for accelerated pad seating after installation, reducing the break-in period
• Low-dust formulation for cleaner wheels

RK Series Rotors:

• Direct-fit OEM replacement dimensions — no modifications required
• Geomet anti-rust surface coating protects against road salt and corrosion
• Fully balanced and runout-tested for smooth, vibration-free braking
• Vented rotor design promotes heat dissipation and reduces brake fade
• High-carbon grey iron construction meets or exceeds factory specifications

What's Included:

• Front brake pads (Ultimax)
• Rear brake pads (Ultimax)
• Front rotors (RK Series)
• Rear rotors (RK Series)
• Caliper lubricant

Renewing both the front and rear braking systems simultaneously ensures balanced stopping performance. Rear brakes contribute up to 40% of total vehicle stopping power — replacing all four corners at once maximizes braking efficiency and safety. EBC manufactures 100% of its brake pad range in its own UK and USA facilities.
