EBC S20K1618 Stage 20 Ultimax Brake Pad & RK Rotor Kit Front and Rear

The EBC S20K1618 Stage 20 Brake Kit is a complete front and rear disc brake solution that bundles Ultimax brake pads, RK series OEM-replacement rotors, and caliper lubricant into a single value package. Renewing both axles at the same time ensures balanced, consistent stopping performance — rear brakes account for up to 40% of a vehicle's total stopping power and are too often overlooked during routine maintenance.

Ultimax Brake Pads:

• Engineered with a patented low-metallic aramid fiber compound (utilizing DuPont Kevlar and Twaron composites) that reduces rotor wear while maintaining strong braking efficiency
• Fully shimmed and chamfered for quiet, vibration-free operation
• Coated with EBC's patented Brake-In™ red-top surface treatment, which scours glaze and heat spots from rotor surfaces for faster, more even pad seating right after installation
• Designed to match OEM dimensions with tight tolerances for proper fit and even wear

RK Series Rotors:

• Direct-fit OEM replacement — no modifications required for installation
• Manufactured from high-quality gray iron with elevated carbon content to reduce brake shudder, heat cracking, and high-frequency vibrations that cause squealing
• Machined to extremely tight tolerances — within 0.05mm — for smooth, runout-free braking
• Finished with a Geomet anti-corrosion coating to resist rust from road salts, moisture, and brine
• Fully balanced and runout-tested from the factory

What's Included:

• Front and rear Ultimax brake pads (complete 2-axle set)
• Front and rear RK series replacement rotors
• Caliper lubricant

The EBC S20K1618 is recommended for normal street driving, high-performance street use, and truck or SUV applications. Replacing all four corners simultaneously delivers the balanced braking performance your vehicle was designed for.
