Wouldn't adding negative angle to your pinion,to compensate for housing rotation,be a moot point on a ladder bar or 4 link car?If the housing is mounted rigidly on solid bars with solid rod ends,it CAN'T rotate.Looks like you would need to set it up for however much your car would squat if your are trying to align everything under load.And that would be next to impossible to predict.Never has made good common sense to me.Maybe one day I'll learn
