1- adj valve
1- 6mm bolt
2- metric butt connectors
2- metric plugs
2- hand built custom adaptors
(they use a metric nut on one end and a US thread nut on the other)

Fits stock 1973-1983 z's. All z's from 70-83 use a 70/30 braking ratio. This makes the back end want to pass the front end in a panic situation. By installing one of these kits you can dial in the braking ratio to a 55/45 which is considerably safer and should decrease your stopping distances.

We hand build these adaptors so it makes this kit a plug'n'play. Otherwise you'd have to cut the hard lines on the car and do a double flare.

We make this kit so that it bolts right on top of the factory proportioning valve.

This is another Z Specialties exclusive. You can buy the valve at a lot of places, but it won't fit your car because all of the valves are US threads and these cars are of course metric.
