I will come out and say that this probably doesn't entirely belong here as it doesn't pertain entirely to Bosses specifically. My dad and I have a project car that we road race, an 86 Fox, and there is an issue with the rear in it, under hard corners the brake pad rubs on the rotor. I know this happens because the rear allows a certain amount of movement from the axle into and out of the housing. I haven't experienced this on my car, so assume Ford has found a way to correct this. My question is: does this partially occur because the PHB allows for more movement side to side of the axle, and if so could it be remedied by a watts link. I only ask on this forum as it seems to have the most people on it that are proficient in car racing and setup.
