EBC S20K1394 Stage 20 Ultimax Brake Pad & RK Rotor Kit (Front & Rear)

The EBC S20K1394 is a complete Stage 20 two-axle disc brake kit that bundles EBC Ultimax brake pads and RK series plain rotors for both the front and rear axles into a single, value-driven package. Compared to purchasing each component individually, this kit delivers significant savings along with the confidence of a fully matched brake system.

EBC Ultimax Brake Pads:

• Formulated with Aramid fiber for high efficiency, low-dust braking performance
• Fully shimmed and chamfered to minimize noise and vibration
• Features EBC's patented Brake-In coating pre-applied to the pad surface, conditioning rotors and delivering effective braking from the very first stop
• Eco-friendly compound free of heavy metals and sulfides

EBC RK Series Brake Rotors:

• Direct-fit OEM replacement dimensions machined to extremely tight tolerances
• Protected by EBC's Geomet anti-rust surface coating for long-term corrosion resistance
• Fully balanced and runout-tested at the factory for vibration-free, smooth braking
• Cast from high-quality gray iron that meets or exceeds OEM thermal and wear specifications

Why Replace Front and Rear Together?

Optimal braking performance depends on all four corners working in unison. The rear brakes contribute up to 40% of total stopping power — renewing both axles simultaneously ensures a balanced, consistent braking response and maximizes the service life of the new components. Each kit also includes caliper lube for a complete, professional installation.
