Since I'm about to get a move on the front suspension, I'll be getting my front brakes soon, and probably all of the lines, but was wondering if I would need a proportioning valve. I'm getting Wilwood's 11" rotor, 4 piston calipers on the front and back, but the front pistons are 1.75" and the rears are 1.12". My question is if this difference is enough of a bias to not need a proportioning valve?
