EBC S20K1685 Stage 20 Ultimax2 Brake Pad and RK Rotor Kit Front and Rear

The EBC S20K1685 Stage 20 Brake Kit is a complete front and rear disc brake pad and rotor package engineered for daily drivers seeking a reliable, direct-fit OEM-quality upgrade. This two-axle kit bundles everything needed for a full brake system refresh, including Ultimax2 pads, RK plain rotors for both axles, and caliper lubricant — delivering a comprehensive solution in a single purchase.

Ultimax2 Brake Pads:

• Constructed with aramid fiber for high-efficiency friction and long pad life
• Fully shimmed and chamfered to minimize brake noise and vibration
• Features EBC's patented Brake-in coating for faster pad bed-in immediately after installation
• Designed for low brake dust output, helping protect alloy wheel finishes
• Denser compound construction distributes braking heat evenly, reducing localized rotor and pad deformation

RK Plain Rotors:

• Direct OEM-replacement fit — no modifications required over stock setup
• Cast from premium G3000 grey iron with high carbon content for strength and durability
• Coated with Geomet anti-rust surface treatment for long-term corrosion resistance against road salts and brine
• Fully balanced and runout-tested at the factory for smooth, vibration-free braking
• Front rotor diameter: 11.0 in. (280mm); FMSI Pad Design: D1252

Kit Includes:

• Front and rear Ultimax2 brake pads (components UD841 + UD641)
• Front and rear RK plain rotors (components RK993 + RK998)
• Caliper lubricant

Renewing front and rear brakes together ensures balanced stopping performance. Rear brakes contribute up to 40% of total stopping power, making a simultaneous two-axle replacement the smart choice for safety and even wear. The EBC S20K1685 is backed by a 10,000-mile no-hassle warranty.
