I have tons of race car pix, but couldn't find the routing of the adj PV inside the car by the driver seat. I'd like to know where the holes are located for the brake lines and is it along the trans tunnel or along the rocker. Pix are appreciated. TIA
I just mounted my adjustable proportioning valve on inner fender apron behind the shock tower near the master cylinder. I don't see the point of plumbing it inside the car.
If it was a track car, the adj PV is for varying track conditions. And, I believe brake lines are safer inside away from road debris + drive-shaft damage.

The lines arent mounted inside the car. When people do this , they just cut the brake line in the tunnel, flare the lines, drill a hole in the tunnel, take the knob off the PV, mount the PV on the lines, poke the knob shaft through the hole amd then reinstall the knob.
Two options here, wilwood and others make a remote mount knob with a long cable to adjust the PV. This is the most common set up you will see.
I mounted mine with the brake line outside the frame rails and have the PV below the floor with the knob inside the car. It is right by my driver seat. I also sealed this with a grommet.
Keep in mind NHRA does not allow any fluid lines to run down the drive shaft tunnel, fuel, brake...etc. the also state that when the brake and fuel line pass by the bellhousing they need to be protected by 1/8" steel or outside the frame rails. Just keep that in mind while you are routing your lines. This is a good set of safety tips to go by, they do it for a reason. Also look into safety tech for track cars. SCCA and NASA rules are not as detailed as NHRA but still have good tech.
i dialed in my brakes by adjusting the proportioner with making consecutive stops. If i notice brake fade in the rear drums I can dial them out to prevent the rears from locking up.
