Fitment Notes

• Rear axle kit only - confirm front axle is also upgraded when installing performance pads to maintain balanced braking.
• All applications are RWD. Does not apply to AWD or FWD configurations.
• Do not remove the thermic black anti-rust coating from rotors prior to installation - it is designed to be swept away by the pads during break-in.

Features

• Redstuff ceramic compound with aramid fiber delivers improved bite and reduced stopping distances compared to OEM pads.
• Up to ~80% less brake dust than stock pads, keeping wheels cleaner between washes.
• Patented EBC Brake-In™ coating on pad surface allows faster bed-in without a traditional hard-stop break-in routine.
• Pads are fully shimmed, slotted, and chamfered for reduced noise and optimized pad-to-rotor contact.
• Premium G3000 gray iron RK rotors meet or exceed OEM thermal, noise, and vibration standards.
• Thermic black GEOMET™ anti-rust coating protects rotors from corrosion without requiring removal before install.
• Rotors are fully balanced and runout-tested at the factory for smooth, vibration-free braking.
• Bundled kit saves cost versus purchasing pads and rotors separately.

Product Description

The EBC S12KR1044 is a rear brake pad and rotor kit engineered for Lexus GS300, GS400, GS430, IS300, and SC430 owners seeking a meaningful upgrade over factory brakes without the mess of heavy brake dust. At its core is EBC's Redstuff ceramic compound - a pad material blended with aramid fiber and ceramic granules that produces significantly less dust than OEM pads while delivering strong, consistent stopping power for street-driven and lightly modified vehicles. The patented Brake-In™ coating pre-applied to each pad accelerates the bed-in process, so drivers experience improved braking performance faster after installation.Paired with EBC's RK Series rotors - precision cast from G3000 gray iron and finished with a thermic black GEOMET™ anti-rust coating - this kit provides a direct bolt-on replacement with no modifications required. The rotors are factory-balanced and runout-tested, ensuring a smooth, judder-free brake pedal feel. This kit covers the rear axle across multiple Lexus platforms sharing the same rear brake architecture, from the IS300 sport sedan to the SC430 grand tourer. For balanced brake system performance, EBC recommends pairing this rear kit with a compatible EBC front pad and rotor upgrade on the same vehicle.
