The proportioning valve revisited ...

[Scott Walshaw]

Dave...I replaced my stock unit with an adjustable after market unit years ago. Very effective for AutoX...not sure these are available any longer and haven't noticed if it's in the catalog. I likely have the original instruction manual, etc. somewhere if anyone's interested in a possible source? Regards, Scott

As Dave mentioned, VW suppliers typically have them.

I just put a Wilwood adjustable valve in my car, as it's significantly non-stock, and that helped get the bias sorted-out.

Years ago when I was actively running races with POC, (race tires) I first replaced the valve with a VW Tee. But that was a Little too much. Rear brake lockup under trail braking. Then I replace the Tee with a small after market adjustable valve (I think it was from racers wholesale, and after a couple of adjustments, it was perfect, and I have not messed with it since.
