Proportioning valve after conversion

A drag race car's use throws a serious wrinkle in the works. With that tire combo the prop valve may actually be needed in the front circuit as with those skinny front tires it is much easier to have too much front brake than too much rear brake..[/QUOTE]


You are correct, I have a adjustable PV on my front brakes on the race car pictured. It has 4 wheel Strange disc.......17" wide rears, 4 1/2" wide fronts

The conversion set up I am describing, is on a street SB Dart, with 15" wheels all around, and slightly larger (read slightly) rear tires.
