Wilwood brake proportioning valves are adjustable between 100 and 3,000 psi (depending on model) with a twist of a knob or the flip of a lever, and most can reduce pressure up to 57 percent. They let you adjust brake bias quickly and easily to compensate for changing track conditions, or for big and little tire combinations.
