EBC S20K1662 Stage 20 Ultimax Brake Pad and RK Rotor Kit Front and Rear

The EBC S20K1662 Stage 20 Brake Kit is a complete front and rear disc brake replacement package, combining EBC's Ultimax brake pads with RK Series OE replacement rotors and caliper lubricant — everything needed to refresh both axles in a single purchase.

Ultimax Brake Pads:

• Built with a patented low-metallic aramid fiber compound (DuPont Kevlar and Twaron composites) for reduced rotor wear without sacrificing stopping power
• Fully shimmed and chamfered to minimize noise, vibration, and contact against rotor lips
• Patented EBC Brake-In™ coating scours existing glaze and heat spots from rotor surfaces during initial break-in, delivering improved grip from the first drive
• Consistent performance across all climates — hot, cold, wet, or dry
• Government R90-tested for equivalent performance, bedding, cold-temperature operation, and speed sensitivity compared to OEM parts

RK Series Rotors:

• Direct-fit OEM replacement rotors cast from G3000 gray iron with a higher carbon content to reduce brake shudder, heat cracking, and high-frequency vibration
• Thermic black anti-rust surface coating for long-lasting corrosion protection
• Fully balanced and runout tested to ensure smooth, vibration-free braking
• Machined to tight OEM tolerances for a precise fit with no modifications required

Kit Includes:

• Front and rear Ultimax brake pads (both axles)
• Front and rear RK Series rotors (both axles)
• Caliper lubricant

Renewing front and rear brakes together ensures balanced, maximum braking performance. Rear brakes contribute up to 40% of a vehicle's total stopping power — replacing both axles at the same time restores full braking efficiency and extends the life of the new components.
