Key Features

The PowerStop Autospecialty Rear Brake Rotor incorporates several advanced features designed to improve your vehicle's braking performance and longevity:

• Direct OE replacement fitment ensures hassle-free installation and compatibility with your Subaru WRX.
• Manufactured with Tru-Cast precision machining for exact OE fit and smooth braking surface.
• Oversized drill holes facilitate heat dissipation, reducing brake temperature and minimizing brake fade during aggressive driving or towing.
• Counter-sunk holes help resist stress risers and cracking, extending the rotor’s service life.
• Corrosion-resistant gold zinc plating provides excellent protection against rust and corrosion, maintaining appearance and performance over time.
• Designed to improve wet weather braking performance, ensuring safety in all driving conditions.

Construction & Design

The PowerStop Autospecialty brake rotor is constructed from high-quality cast iron, ensuring durability and reliable performance under demanding driving conditions. The rotor features a precision-machined surface that guarantees a smooth contact patch with brake pads, promoting even wear and consistent braking feel. The oversize drill holes are strategically placed to enhance heat dissipation, which helps maintain optimal braking performance during extended use or aggressive driving.

The corrosion-resistant gold zinc plating not only enhances the rotor's appearance but also provides a protective barrier against moisture and road salts, significantly reducing the risk of rust and corrosion. The counter-sunk design of the drilled holes adds structural integrity, preventing stress risers that could lead to cracks, especially during high-stress braking scenarios.

Performance & Sound

Designed to improve stopping distance and pad bite, this rotor offers a noticeable upgrade over standard factory components. The precise machining and heat management features contribute to more consistent braking performance, reduced brake fade, and improved pedal feel. While it is optimized for street use, the rotor's robust construction also makes it suitable for spirited driving and light track days, providing confidence-inspiring braking power and reduced noise during operation.
