I did exactly that. Changed my front rotors, pads and calipers to a performance brand, PowerStop or EBC I think. It was a while ago. Slotted and drilled rotors, better composition pads, think they were OEM calipers. Changed all the lines to Stainless, and replaced every component in the entire rear drum setup. Car makes 500hp and granted I don’t road race, but with ‘spirited’ street driving I have never not had enough brake pedal.
