Product Description

The EBC S12KR1309 Stage 12 rear brake kit is a complete performance and replacement upgrade designed specifically for the 2010-2012 Lexus HS250h hybrid sedan equipped with the 2.4-liter I4 engine. This kit pairs EBC's low-dust Redstuff ceramic brake pads with premium RK smooth rotors to deliver improved stopping power and cleaner wheels compared with many standard rear brake setups. The aramid fiber-enhanced pad compound helps provide strong engagement during everyday driving and spirited street use, while the patented Brake-In coating accelerates the bedding-in process for consistent performance shortly after installation.

Included RK rotors are coated with a durable anti-rust finish and are fully balanced and run-out tested to help reduce vibration and extend service life. Designed as a direct OEM-style replacement for the rear braking components, installation requires no modifications to existing calipers or mounting hardware. Fitment is confirmed for 2010 through 2012 Lexus HS250h models; coverage beyond these years is unconfirmed at time of listing. This rear brake kit is ideal for Lexus owners seeking a performance-minded retrofit that enhances brake feel, reduces dust, and improves overall rear braking performance.
