I am certain I will (math doesn't lie). The main reason is the Wilwood's thinner hat material (.25" aluminum) as compared with the OEM hat material thickness of .293". This is about .040" that gets at least the outboard face in the same plane as the OEM rotor. The reason why this is so critical is because my calipers are very close to the three-piece wheel assembly bolts, so the caliper cannot be allowed to move any further outboard. Being the calipers are mounded inboard of the brake mounting boss on the upright, this allows me to shift the caliper inboard by any amount I want to, so this will end up being pretty flexible, and allow me to burn up some cheap OEM rotors with extremely aggressive pads on track day, and then run the super-light rotors with street pads in between track days.
