Very nice wheel choice, congrats. Decent price too @ $900-$1000 a set. Certainly a better design than the CSL reps: look better, more air flow and easier to clean. Those weigh in at about 8.5-9 kg's each, nice and light.
I'm planning on fitting these to my N54 135i, one can get aggressive offsets with them still nicely tucking ever so slightly inside of the fenders (staggered). I'm a little more partial to the matte gunmetal but I see this is a special order colour and so might just roll with the silver for the road and my CSL reps in gunmetal for the track.
Question: did you try to balance those rims without tyres? I suspect they required some weights to balance properly? For this price point I don't expect perfection (I'd then look to OZ's if the case for a reasonable price point).
BTW, I like the cap design, their logo is a very nicely designed symbol - it's nice to have custom wheels - why bother with boring old BMW centre caps?
