EBC S20K1018 Stage 20 Ultimax Brake Pads and RK Rotors Front and Rear Kit

The EBC S20K1018 Stage 20 Brake Kit is a complete front and rear disc brake solution, pairing EBC's Ultimax2 brake pads with premium RK Series plain rotors for both axles. Engineered as a direct OEM replacement, this two-axle kit delivers consistent, confident stopping power for daily drivers including cars, trucks, and SUVs.

The Ultimax2 brake pads are built with high-efficiency aramid fiber construction, fully shimmed to minimize noise and vibration, and chamfered for precise fitment. Each pad features EBC's patented Brake-in coating, which accelerates the pad bed-in process for optimal braking performance immediately after installation.

The EBC RK Series rotors are machined to OEM factory dimensions with extremely tight tolerances of less than 0.05mm. Constructed from high-quality gray iron with an elevated carbon content, they are engineered to reduce brake shudder, heat cracking, and high-frequency vibrations. Each rotor features a Geomet anti-rust surface coating for long-term corrosion resistance and is fully balanced and runout-tested prior to shipping.
