Product Details

The EBC S20K1637 is a complete Stage 20 front and rear disc brake kit that pairs Ultimax2 brake pads with RK series OEM-replacement rotors for a full two-axle brake system refresh in a single purchase. Bundling all four corners together delivers a balanced, optimized braking system and significant savings over purchasing components separately.

Ultimax2 Brake Pads:

  • Constructed with aramid fiber reinforcement for high-efficiency friction performance
  • Fully shimmed and chamfered for quiet, vibration-free operation
  • Treated with EBC's patented Brake-In coating for accelerated pad bedding immediately after installation
  • Low-dust, street-optimized compound suitable for everyday driving

RK Series Rotors:

  • Direct-fit OEM replacement design for straightforward installation
  • Thermic black anti-rust surface coating protects against corrosion
  • Fully balanced and runout-tested at the factory for smooth, vibration-free braking
  • Manufactured to meet or exceed original equipment specifications

Why Replace Front and Rear Together?

  • Rear brakes contribute up to 40% of total stopping power — often overlooked during routine service
  • Renewing all four corners simultaneously ensures consistent, balanced braking performance across both axles
  • Eliminates uneven wear and braking imbalance caused by mismatched component ages

Kit Includes:

  • Front brake pads (Ultimax2)
  • Rear brake pads (Ultimax2)
  • Front rotors (RK series)
  • Rear rotors (RK series)
  • Brake caliper lubricant

The EBC S20K1637 is engineered for drivers who want a reliable, complete OEM-quality brake overhaul with the added benefit of EBC's proven friction technology and corrosion-resistant rotor coating.
