Fits select 1998-2010 Lexus GS300, GS400, GS430, IS300, and SC430.

The EBC Brakes S4 Series kit S4KR1057 is a high-performance street upgrade engineered for premium imports and muscle cars. This comprehensive kit pairs EBC Redstuff ceramic brake pads with USR fine-slotted rotors to deliver increased stopping power and thermal stability while maintaining significantly lower dust levels than original equipment components.

The Redstuff pads utilize an aramid fiber-enhanced ceramic compound that is fully shimmed, slotted, and chamfered for quiet operation. Each pad is finished with EBC’s patented Brake-in coating to accelerate the seating process after installation. The USR sport rotors are cast from G3000 iron and feature narrow-slotted venting to promote cooler operating temperatures and ensure flat, parallel pad wear. The rotors are finished with a Geomet black anti-rust coating to maintain a clean appearance and resist corrosion.
