EBC S20K1670 Stage 20 Ultimax Brake Pad and RK Rotor Kit Front and Rear

The EBC S20K1670 Stage 20 Brake Kit is a complete front and rear disc brake solution, bundling EBC's proven Ultimax brake pads with direct-fit RK series rotors and caliper lubricant in a single, value-packed package. Renewing both axles at the same time ensures balanced, optimized braking performance across the entire system.

Ultimax Brake Pads:

• Constructed with a blend of synthetic aramid fibers and metallic filament for extended pad life and consistent friction
• Fully shimmed and chamfered to minimize brake noise and vibration
• Features EBC's patented Brake-In™ coating for faster, more uniform pad seating right after installation
• Pre-fitted anti-noise shims with a center-line slot to keep braking quiet during everyday driving
• Designed for non-sport urban daily driving on sedans, SUVs, and light trucks

RK Series Rotors:

• Direct-fit OEM replacement rotors — no modifications required
• G3000 high-carbon gray iron construction reduces brake shudder, heat cracking, and high-frequency vibration
• GEOMET™ anti-rust surface coating protects against road salt and corrosion
• Fully balanced and runout-tested at the factory for smooth, vibration-free braking
• Machined to tight OEM tolerances for a precise factory-style fit

What's Included:

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

Rear brakes contribute up to 40% of total stopping power — replacing front and rear components together with the EBC S20K1670 ensures the entire braking system works at peak efficiency. This kit is backed by EBC's 1-year / 10,000-mile limited warranty against defects in materials and workmanship.
