by my reckonings they should stick it fine man. stock calipers fit under 14s, which i like, and the stoppin power from the lines, pads and discs and the BMCS i already have should be fairly good. i'd only consider somethin more potent if i wanted to go way over 200bhp tbh, but thats just me. tbh, driving style will have alot to do with it, and being a qualified advanced driving observer, i shouldnt be up people's ass to need MASSIVE brakes anyway lol! i dont really drive on my brakes, nor do i know how people do it, scares the bollox outta me.
