So what's people's thoughts on upgrading the calipers on a RR6? Is it worth doing and what do you suggest? I've already got Hel braided lines. I've heard a lot of people recommend Brembo M4s and heard good things about the new Hel performance kit. But did see a post on here about the accossato calipers from BDS. I can't seem to find the size online, so are the calipers 100mm or 108mm.
