Allows precise adjustment of front/back braking effort. Furthermore if fitted within reach of driver it can be used immediately after leaving the pits according to weather conditions - a significant improvement on handling particularly on hard braking entering a bend. Aids brake tuning and control.
Before purchasing please ensure this performance enhancement is allowed in your race series as it wouldn't be allowed in most historic racing.

Alloy knob for vernier adjustment
Inlet & outlet ports 1/8"NPT
Range 100 - 1200 psi

Please note that professional installation is required. As with most car parts it is supplied without instructions, as fitment would depend on your precise application. I am unable to answer questions or give technical advice about the suitability of fitment to your project or foresee all the issues that may arise in individual applications.
