V40 320mm Brake Upgrade?
 

I've seen people talking about 320mm Brake upgrades on Volvo's.. Both C30s & S40s, and some on V40s, but not so much information on that. Anyway, my 2.0D has been remapped and I would like more stopping power. My car has the standard 178mm brakes found on 1.6Ds & lower trim 2.0Ds. It's pretty easy to find 300mm calipers & discs, but I'm striking out on 320mm.. so I'm starting to wonder if it's even a thing. Is this doable? Will Focus ST brakes work? Has anyone got any information on the V40?
