Looking for any help on information, I've done some research but can't come to a actual conclusion I have the single piston calipers and regular rotors and I'm looking to possibly swap to the Ralliart bigger two piston calipers and larger diameter rotors the bolt pattern is the same but what I can't figure out is if the mounting holes line up or if I would need to change the break booster or reservoir again any help will be greatly appreciated as I'm trying to get this resolved and done before the week end
