Adjustable Brake Proportional Valve - (NA/NB 1989-2004)

One of the best ways to get the most out of your brakes is to adjust the brake proportioning or bias. The ideal brake bias depends on your ride height, the amount of traction you have (both due to your tyres and the surface you're driving on), and the specification of your braking system. You always want the front brakes to lock up first for stability reasons, but Mazda was extremely conservative and so the rears never have a chance to make much of a contribution. This adjustable proportioning valve allows you to adjust your brake bias for the perfect setup. The valve allows you to adjust the rear line pressure from 43% to 100% of the front.

The kit includes everything you need to make installation very easy. No flaring or line bending required! The fittings are made of brass to ensure a better seal both on the flare and the tapered pipe threads when compared to harder materials. Compatible with all 1990-05 except those with both factory-installed Sport brakes and ABS. If your car has ABS but not the Sport brakes, this proportioning valve kit will still work for you. This kit is for NA and NB MX-5s. 

Includes:

  • Wilwood proportioning valve
  • M10 inverted flare to NPT adapters - FM exclusive parts!
  • M10 inverted flare union
  • Loctite 545 Thread Sealant
