Hawk HB800C.670 HPX Autocross Competition Brake Pads

The Hawk HB800C.670 HPX brake pads are engineered specifically for autocross competition, delivering the unique performance characteristics demanded by this distinctive racing discipline. Designed to fit Wilwood 6617 (W4A/W6A) calipers, these pads represent Hawk's commitment to providing autocrossers with a purpose-built solution rather than adapting street or track compounds.

Key Features:

• HPX compound engineered specifically for autocross competition use
• Smooth bite with clean modulation and quick activation
• Predictable braking power in both warm and cold conditions
• Proprietary friction material optimized for autocross demands
• Designed for Wilwood 6617 caliper applications
• Competition-use only compound (not for street use)

The HPX compound was developed through extensive R&D spanning over two years, working directly with SCCA Solo Nationals-winning competitors to identify the most desirable characteristics for autocross success. This competition-grade compound provides the communication between driver and braking system that's critical for competitive advantage, regardless of class or tire choice. As with all Hawk Motorsports compounds, HPX is strictly for off-highway competition use only.
