Hawk HB658C.570 HPX Autocross Competition Brake Pads

The Hawk HB658C.570 HPX brake pads represent Hawk Performance's first autocross-specific friction compound, engineered exclusively to dominate the unique challenges of competitive autocross racing. Unlike street-capable compounds, the HPX is designed strictly for off-highway competition use, delivering the precise braking characteristics demanded by serious autocross competitors.

Autocross-Optimized Performance:

• Predictable smooth initial bite for confident turn-in and threshold braking
• Clean modulation and quick activation for precise brake control
• Medium torque, medium temperature friction compound optimized for autocross deceleration rates
• Consistent performance warm or cold—critical for co-driving and quick run sequences
• Superior communication between driver and braking system for competitive advantage

Key Features:

• Hawk's proprietary HPX friction material developed through extensive field testing
• Validated through rigorous dynamometer and real-world autocross testing
• Engineered specifically for the demands of autocross braking scenarios
• Works effectively regardless of vehicle class or tire choice
• Designed for iron/metal rotors (not compatible with carbon ceramic rotors)

The HPX compound underwent over two years of development in collaboration with Solo Nationals-winning competitors to identify the most desirable characteristics for autocross competition. This motorsports-only compound provides the controllability and consistency that champions rely on to deliver precise stopping power exactly when needed, making it the superior choice for serious autocross competitors seeking a clear competitive edge.
