Product Details

The EBC S20K1878 S20 Kits combine high-performance Ultimax brake pads with precision-engineered RK rotors for complete front and rear brake system renewal. This comprehensive 2-axle kit provides everything needed to restore maximum braking performance across your entire vehicle.

Ultimax Brake Pads:

  • Advanced Aramid fiber construction for superior stopping power and durability
  • Fully shimmed and chamfered design reduces noise and vibration
  • Patented EBC Brake-in coating accelerates bedding process for faster break-in
  • Low dust formulation keeps wheels cleaner

RK Rotors:

  • Direct-fit OEM replacement design ensures proper fitment
  • Geomet anti-rust surface coating provides long-lasting corrosion protection
  • Precision balanced and runout tested for smooth, vibration-free braking
  • Premium grade castings meet or exceed OE specifications

Complete Kit Includes:

  • Front brake pads and rotors
  • Rear brake pads and rotors
  • Caliper lubricant

Renewing both front and rear brakes simultaneously ensures balanced braking performance, as rear brakes contribute up to 40% of your vehicle's total stopping power. This kit offers significant savings compared to purchasing components separately while guaranteeing matched performance across both axles.
