Product Description

The **EBC S4KR1115 Rear Brake Kit** pairs EBC's Stage 4 Redstuff ceramic brake pads with USR sport vented slotted rotors to deliver a performance-oriented rear braking upgrade for select Subaru Impreza and WRX/WRX STI models from 2008 through 2017. Redstuff ceramic pads are formulated to generate strong, consistent braking performance with **lower dust output** than many traditional pad materials, making them a popular choice for street drivers who want both performance and cleaner wheels. The vented and slotted rotor design helps manage heat and evacuate brake gases, debris, and water for improved pedal feel and reduced fade under spirited driving.

Designed as a **direct, bolt-on replacement** for rear brakes on compatible Subaru models, this kit uses factory mounting points so installation is straightforward for DIY mechanics and professional shops alike. The thermic black and GEOMET anti-rust coatings on the rotors provide enhanced **corrosion resistance**, helping maintain appearance and performance over time. Backed by a 12-month/10,000-mile limited EBC warranty (excluding heavy competition or track use), this kit is ideal for drivers seeking a balance of **performance, durability, and everyday usability** from their brake system upgrade.
