EBC S1KF1003 S1 Brake Kit with Ultimax Pads and RK Rotors

The EBC S1KF1003 is a complete brake kit that combines quality Ultimax2™ brake pads with gray RK rotors and caliper lube, offering an affordable alternative to purchasing components separately. This front brake kit delivers reliable stopping power for daily driving applications.

Ultimax2™ Brake Pads:

• Features red brake-in surface coating for instant safe braking after installation
• Non-metallic pad containing zero steel fiber, making it cleaner and less aggressive to cast iron rotors
• Graded Code N by USA brake ratings with GG friction rating for environmentally friendly status
• Nominal friction coefficient 0.46 with minimal rotor damage and similar dust to original parts
• No shims needed for noise reduction

RK Rotors:

• Direct fit OEM replacement with thermic black anti-rust surface coating
• Fully balanced and runout tested for smooth braking performance
• Machined to extremely tight tolerances of less than 0.05 millimeters
• High-quality gray iron features higher carbon content to reduce brake shudder, heat cracking, and high-frequency vibrations

Disc wear is reduced by up to 50% compared to more abrasive semi-metallics, with rotors commonly lasting two sets of pad lifetimes. This S1 kit provides an excellent balance of performance, longevity, and value for vehicle owners seeking a reliable brake system upgrade.
