Product Details

The EBC S20K1678 Stage 20 Brake Kit is a complete front and rear brake system solution, bundling EBC's proven Ultimax2 brake pads with direct-fit RK rotors in a single, value-packed kit. Renewing both axles at the same time ensures balanced, consistent stopping performance — and since rear brakes contribute up to 40% of total stopping power, addressing both ends together simply makes sense.

Ultimax2 Brake Pads:

  • Constructed with aramid fiber for high efficiency and long pad life
  • Fully shimmed and chamfered to minimize brake noise and vibration
  • Feature EBC's patented Brake-In™ coating for accelerated pad seating right after installation — no lengthy break-in procedure required
  • Low dust formulation for cleaner wheels

RK Series Rotors:

  • Direct OEM replacement fit — no modifications required
  • Coated with EBC's Geomet anti-rust surface treatment for long-term corrosion resistance against road salts and brine
  • Fully balanced and runout tested at the factory for vibration-free, smooth braking
  • Manufactured from high-carbon grey iron for strength and durability

What's Included:

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

The EBC S20K1678 kit delivers a cost-effective upgrade over purchasing pads and rotors separately, making it the ideal choice for drivers looking to restore or improve everyday street braking performance across both axles in a single service.
