EBC S20K1512 Stage 20 Ultimax Brake Pad and RK Rotor Kit Front and Rear

The EBC S20K1512 Stage 20 Brake Kit is a complete front and rear disc brake solution that bundles Ultimax2 brake pads, RK series plain rotors, and caliper lubricant into a single value package — saving you the cost of purchasing each component separately.

Ultimax2 Brake Pads:

• Engineered with a patented low-metallic aramid fiber compound (incorporating DuPont Kevlar and Twaron composites) to reduce rotor wear while maintaining excellent stopping efficiency
• Fully shimmed and chamfered to minimize brake noise, vibration, and judder
• Centerline slot design helps prevent heat expansion and reduces noise during braking
• Patented EBC Brake-In coating scours off glaze and heat spots from the rotor surface on first use, delivering proper brake seating faster after installation
• Designed to match OEM dimensions with tight tolerances for a direct, rattle-free fit

RK Series Plain Rotors:

• Direct OEM replacement fit — no modifications required
• Cast from high-carbon gray iron for superior resistance to heat cracking, brake shudder, and high-frequency vibration
• Vented center design promotes airflow between rotor faces for cooler, more consistent braking
• Thermic black anti-rust surface coating protects against road salt, brine, and corrosion
• Fully balanced and runout-tested at the factory for smooth, vibration-free braking performance

What's Included:

• Front and rear Ultimax2 brake pads
• Front and rear RK series plain rotors
• Caliper lubricant

Renewing both axles at the same time ensures balanced stopping power across the entire braking system. Rear brakes contribute up to 40% of total stopping power — replacing pads and rotors front and rear together delivers maximum, consistent braking performance for everyday street driving.
