I think that probably has more to do with wheel design than brakes themselves because as far as I know the 335is brakes are exactly the same as a 335i. I had a 335i and it produced the normal extreme amounts of brake dust that BMWs always do. Either way that is great news, maybe I should get a set of 335is wheels for my car.
Oh, and +1 on the emoticons. I've never seen so many in one post before.
