Jonny,

Having run 330's with Brembo's for many years, as you know, I'd say they are massive overkill. Fancy yes, but really not needed in my opinion.

If I was going to do it again from scratch, I'd go for 300mm discs and simple Brembo or AP 4-Pots, or similar.

As soon as you get into 330's, 17's become a must really and the extra 30mm of brake disc size just isn't worth having to run 17's IMO.

As for looking fancy, I think 300mm discs with 4-Pots look proportionally as good as 330's do behind 17's.
