Trackspeed Brake Prop Valve Kit


Trackspeed's Adjustable Proportioning Valve Kit is a must-have item for anyone looking to shorten stopping distances and maximize braking potential on a Mazda Miata. It replaces the factory proportioning valve with an adjustable unit, which allows you to dial in the brake bias to suit your conditions and uses. The kit also includes two 1/8" NPT to M10x1.0 inverted flare brass adapter fittings, eliminating the need for an expensive flaring tool - simply remove the old valve and install the new one. 

Our kit includes a Wilwood adjustable proportioning valve, two high-quality brass adapter fittings, and a union fitting.
