Hi, I've been looking into brake upgrades for my S2000, a lot of people seem to go for Spoon calipers on Std disks or an aftermarket set-up, which isn't cheap. I've had a dig on the net and some guys in the U.S have been fitting the 350Z/04 impreza calipers. Anyone had much success over here in the UK?
cheers!
