Product Description

The EBC S4KR1057 Stage-4 rear brake kit is engineered for select Lexus models including GS300/GS400/GS430, IS300, and SC430 (1998-2010 depending on model). This direct OEM-fit kit pairs Redstuff ceramic pads with USR G3000 slotted rotors to deliver improved stopping power, reduced brake dust, quiet operation, and excellent fade resistance under spirited or street use.

Featuring 308 mm solid rotors with fine G3000 slots and durable Geomet anti-corrosion coating, the kit excels in heat dispersion and environmental protection. The Brake-In™ pad coating allows rapid bedding in, while rotors are dynamically balanced and run-out tested for smooth, reliable braking. Pads include shims and chamfers to minimize noise and vibration. Installation is simple, requiring no modifications when replacing rear axle components. Fitment is confirmed through 2005 (GS and IS) and 2010 (SC430); later-model vehicles are not supported.
