Power Stop Z23 Evolution Sport Front Brake Kit for Select Subaru 2006-2021 (K4603)

Fits select 2006-2021 Subaru B9 Tribeca, Legacy, Outback, Tribeca, and WRX.

The Power Stop Z23 Evolution Sport Brake Upgrade Kit is an engineered solution for drivers looking to improve the stopping power of their daily-driven Subaru without a complicated installation. This complete front-axle kit replaces worn factory components with a high-performance bolt-on system designed to reduce brake fade and eliminate excessive dust.

The heart of this kit is the Z23 Carbon-Fiber Ceramic compound. This specialized formula offers significantly higher thermal stability than traditional ceramic pads while maintaining a low-dust profile—validated in third-party testing to produce 30% less dust than OE pads on average. These are paired with drilled and slotted rotors that facilitate rapid degassing and cooling, finished with a silver zinc plating to prevent corrosion on non-friction surfaces.

• Carbon-Fiber Ceramic Z23 brake pads for enhanced bite and thermal performance.
• Drilled and slotted rotors for maximum heat dissipation and debris removal.
• Silver zinc plating protects rotors against rust and oxidation.
• Multi-layer rubberized shims help insulate noise for virtually silent braking.
• Premium stainless-steel hardware kit and high-temperature lubricant included.
• Manufacturer Part Number: K4603
