Hawk HPS (High Performance Street) pads offer a tremendous improvement in braking distance over the Subaru's OEM pads. Hawk's unique Ferro-Carbon formula was developed for street performance using the safety and quality of Aerospace and Motorsports severe-duty friction technology. The HPS compound offers a high coefficient of friction and can provide you 20-40% more stopping power and improved resistance to fading over Subarus's OEM replacement pads. HPS's Ferro-Carbon compound provides your Subaru with increased stopping power, long-life, less dust and reduced noise compared to other after market performance brake pads. All Hawk Performance products provide a limited lifetime warranty, ensuring products to be free of defects from manufacturer's workmanship and materials. Hawk HPS pads are designed primarily for a daily driven Subaru but will hold up under light autocross duty as well. Be sure to check your pad size and shape to confirm before you order.
