The stock valve by the pass side rear axle is really a “shutoff valve”. As the axle dops, it limits the amount of pressure, this makes the rear brake pressure non linear. With the track suspension, the coupe has virtually 0 diver under braking, so the stock valve is pretty useless. I don’t have an accurate way of adjusting rear pressure.
So I added 2 Wilwood proportioning valves. The coupe has 2 lines going to the rear so I had to use 2 valves. Now I have linear pressure to the rear and is easily adjustable by poping the hood. I painted the knobs so you can see their position.
