Product Details

PowerStop CRK8496 is part of the Z17 Evolution Geomet Coated Rotor Brake Kit line, a product family focused on straightforward brake replacement for daily-driven vehicles. For Subaru WRX and Subaru WRX STI rear brake service, the Z17 Evolution formula pairs ceramic pads with coated rotors to help maintain consistent stopping feel while limiting dust buildup and rotor corrosion. The rear rotors use a Genuine GEOMET 360 coating, and the pads include shims to help reduce brake noise during normal street driving.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Kit Can Address

• Worn rear brake pads causing reduced braking response
• Brake dust buildup on wheels from older pad material
• Brake noise such as squeal or light vibration during stops
• Surface rust and corrosion on exposed rear rotors
• Brake service needs on a 2024 Subaru WRX or 2018-2021 Subaru WRX STI

Installation Notes

Verify rear fitment by year, make, model, and position before installation. Inspect calipers, slides, and brake hoses during service, and follow factory torque specifications and bedding procedures after installation. This kit is intended for rear brake replacement on the listed Subaru applications.

Quality Assurance

PowerStop validates the low-dust pad formulation through third-party on-vehicle testing in the USA. The rotors are built to OE specifications and protected with Genuine GEOMET coating to help maintain appearance and corrosion resistance in service.
