where have you read it's 50/50.....if it was 50/50 you'd be leaving skid marks from your rear tires every time you stopped and don't try to drive it in the rain.

If it was 50/50 you wouldn't really need a combination valve. 4 wheel drums are 50/50 and there is no normal or "emergency" braking. Even with disc/drum or 4 wheel disc there is no normal or "emergency" braking feature.
Most of the weight of the car is biased towards the front, even under light brake application the nose will tend to dip. If braking were 50/50, everything would have equal sized rotors, caliper bores and pad sizes. I started with my prop valve fully open and even looking at the brake pedal at low speed (10-15 mph) locked the rears. I would say on my car it's adjusted closer to 70-30.
Matthew you have really over thought this , the proportioning Valve you bought is over kill and now it's causing a ripple effect. Send it back and get one that fits your lines.
Also buy a simpler one or a factory one that fits your car that's adjustable.

i just dont want to fw the prop valve like if you lose too much pressure itll block off the whole line, that bugs me which is why i want the wilwood.
plus my rotors are going to be bigger i dont see how i could use a stock proportion valve with fatty rotors in front
Matthew, the rotors being bigger is not really involved in the equation. Pressure and clamping force are. Really, the reason larger rotors are desired is because they will dissipate heat more easily than smaller ones as a function of surface area and mass.
The better stopping ability comes from more clamping force (due to multiple pistons with increased surface area for fluid to push against in the calipers), the resulting larger friction surfaces with increased caliper size, and the ability to remove the heat.

Because your putting disc brakes on the back , yes you'll need a adjustable proportion valve, but it doesn't fit your lines. So you either need to find adapters for the lines , get a different proportion valve or master cylinder. Cheapest is send the expensive proportion valve back and get one geared for your car and with lines that fit. There is many cheaper ones that fit your car.
