Hawk Performance HPX

The HPX compound is engineered for the high-intensity demands of Autoslalom, delivering confident responsiveness, clean modulation, and predictable braking power across a wide range of temperatures and surface conditions. Designed for the mix of low-speed precision and rapid transitions common to slalom driving, HPX provides a smooth, predictable initial bite and rapid activation whether pads are cold or warmed from repeated runs.

Consistent feel: Maintains repeatable brake response during stop-and-go cycles.
Predictable modulation: Enables precise control over braking force for accurate inputs.
Wide operating range: Formulated to perform over broad temperature swings.
Tested performance: Validated through rigorous dynamometer testing for reliability under repeated use.
Suitable for all skill levels: Delivers usable stopping power for novices and experienced competitors alike.

*Installation/compatibility note: Operating temperature range 37–370°C. Optimal temperature range 37–315°C. Designed for Autoslalom and events requiring frequent, repeatable braking; verify fitment for your vehicle application before installation.
