Well, finally finished with swapping 98 Cobra suspension into my 92 and I'm very pleased with the outcome. As you can see the 98 spindles look perfect, stance is exactly how I pictured it, and everything just feels so much better. Except...I used a SBBC proportioning valve in the rear line and I seem to be confused about the setting. During the bleeding of the back brakes I turned the valve to full increase and no fluid came out. Am I just thinking of this backwards? I thought full increase would mean the maximum fluid going thru. I have it installed right (in and out). Also now that everything is back together and aligned there seems to be a feeling of something rubbing. Nothing even comes close to the tires unless I crank the wheel full both ways. Guys at Les Shawb could find nothing, so I'm curious as to what this could be? Bearings are the only thing that comes to mind. I did not change out the hubs. This rubbing feeling only seems to happen as I take off and turn slightly. Any ideas would as always be appreciated.

Increase reduces flow.

Ypu want to unscrew the valve (full decrease) and then bleed the brakes. Then set from there. With cobra brakes on mine, I think mine is 2 turns in.

As far as the feeling of something rubbing maybe you are getting some rub when the car squats upon acceloration perhaps ?

Nope it's the front when you barely turn either direction and goes away after it gets to 10 mph. I did notice that there was no adjustment made wwhere the strut goes thru the bearing on the caster/camber plate. I centered them up and they are still in that position. Thanks for the clarification on the pv. Seems basakwards to me but that is how I ended up bleeding the brakes.
