Hawk HPS (High Performance Street) pads offer a significant improvement in braking distance over OEM pads. Hawk's unique Ferro-Carbon formula was developed for street performance by aerospace and motorsports engineers. The HPS compound offers a high coefficient of friction and can provide you 20-40% more stopping power and improved resistance to fading over BMW's OEM replacement pads. HPS's Ferro-Carbon compound provides your E36 M3 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 E36 M3 but will hold up under autocross duty as well.
