For years we’ve been customizing be-spoke in-cabin Brake Bias system for our track-focused builds. However, that is usually not very viable for most on-road end users. Now, we’ve came up with a more approachable, and easy-to-install Adjustable Brake Proportioning kit for Miata owners! Further enhancing the adjustability of your Miata by biasing your brakes’ front-to-rear proportion. A must-have for those who are looking to fine-tune the characteristics of their braking behavior according to the driver preference, car set-up, course, climate, & weather requirement.
 
Comes with everything needed:
1 x Proportioning valve unit
1 x Male-Male brake line adaptor fitting
2 x Male-Female brake line adaptor fittings (for Miata application)
