I've added the V50 in, although it's not great as I can't find information on specifically which models had which disc (only that the T5 had 300mm and an optional 320mm, and all AWD models had 320mm ones). I'd wager it's the same as the S40 Mk2, but they do sometimes have bigger brakes for estate models.
I'll say that it's as accurate as I've been able to find in the various brake disc catalogues I've found. Definitely worth double checking with the parts compatibility stuff on other sites before buying.
It's also worth noting that there's some variation in some of the dimensions between different brake disc manufacturers (usually in things like overall height, and by less than 1mm). Either the data they give is different to what they manufacture, or stuff like surface coatings add thickness that's different to competitors. Where I've found variation that's more than a few tenths I've added a comment
