Upgrade the braking performance of your Subaru Impreza with the PowerStop Evolution Drilled and Slotted Rear Rotors, part number JBR1366XPR. Designed as a direct OE replacement and sold as a pair, these rotors provide improved cooling and reliable friction performance without requiring special modifications. They are engineered to fit select 2008–2014 Subaru Impreza applications, helping deliver consistent braking for daily driving and demanding conditions.
Precision cross-drilled holes promote heat dissipation, while chamfered drill holes and rounded slots help minimize stress cracking. The slotted friction surface continuously sweeps away brake gases, dust, and moisture to help maintain a clean, consistent contact patch between the rotor and brake pad. This design supports responsive braking performance and helps reduce the effects of heat buildup during repeated stops.
Each PowerStop JBR1366XPR rotor is manufactured to strict tolerances for disc thickness variation and runout, supporting smooth and quiet operation. The weight and vane count match the original equipment design, and the rotors are 100% dynamically mill balanced for dependable rotation. A silver zinc dichromate plating helps resist rust and corrosion on exposed surfaces, making these rotors a practical bolt-on upgrade for stock braking systems.
