EBC S20K1522 Stage 20 Ultimax Brake Pad and RK Rotor Kit Front and Rear

The EBC Stage 20 Kit (S20K1522) is a complete front and rear disc brake pad and rotor replacement kit designed for daily-driven cars, trucks, and SUVs. This two-axle kit bundles everything needed for a full brake service into one convenient package, including Ultimax2 brake pads, RK Series rotors, and caliper lubricant.

Ultimax2 Brake Pads

• Constructed with Aramid fiber for high strength and durability
• Fully shimmed and chamfered to minimize noise, vibration, and judder
• Patented EBC Brake-In™ coating accelerates pad seating after installation for faster, more consistent performance out of the box
• Consistent braking performance in all conditions — hot, cold, wet, or dry

RK Series Rotors

• Direct-fit OEM replacement — no modifications required
• Cast from G3000 high-carbon grey iron for strength and longevity
• Thermic black anti-rust surface coating protects against corrosion, road salt, and brine
• Fully balanced and runout-tested for smooth, vibration-free braking
• Vented rotor design promotes heat dissipation and reduces pad fade

Why Replace Front and Rear Together?

Balanced braking requires all four corners of your vehicle to be working in sync. The rear brakes contribute up to 40% of your vehicle's total stopping power — replacing front and rear simultaneously ensures even wear, consistent brake bias, and maximum stopping efficiency.

Kit Includes:

• Front Ultimax2 brake pads
• Rear Ultimax2 brake pads
• Front RK Series rotors (pair)
• Rear RK Series rotors (pair)
• Caliper lubricant
