Hawk HB630C.626 HPX Autocross Competition Brake Pad Set

The Hawk HB630C.626 HPX brake pad set is engineered specifically for autocross competition, delivering the precise braking characteristics demanded by this unique motorsports discipline. Unlike street-oriented compounds, HPX is designed exclusively for off-highway competition use where smooth bite, clean modulation, and quick activation are critical for performance.

Key Features:

• Autocross-specific compound formulated for cold and warm performance
• Smooth bite characteristics for predictable braking under competition conditions
• Clean modulation and quick activation for precise control during runs
• 0.626-inch pad thickness specification
• Competition-use only compound not suitable for street driving
• Designed for iron and metal rotors (not compatible with carbon ceramic rotors)

Hawk Performance developed the HPX compound through over two years of rigorous research and development, working directly with Solo Nationals-winning autocross competitors to identify the most desirable braking characteristics for competitive advantage. This ferro-carbon formulation addresses the unique deceleration rates, mechanical grip requirements, and drivability demands of autocross competition, offering superior performance compared to street pads or general performance compounds.

Important: HPX is strictly an off-highway, competition-use only compound and should not be used for street driving, even to and from events. This motorsports compound requires proper bedding procedures and is designed for vehicles with iron or metal brake rotors.
