Beyond safety, there are some very distinct performance advantages which are NOT appropriate to allow in IT.
Buy a prop valve, learn how to work on brake systems... or go race a Showroom Stock car.
Matt's dead-nuts right, most cars with ABS now have the proportioning done by the ABS system. Of course, there's plenty of IT-legal ways to screw up the proportioning on a non-ABS car anyway. You gotta have the technical side down, or pay someone else to do it, kids.
