Your car is just amazing!!
But I hesitate between BBS's and the 403M! I love the BBS, I also thought to mount the same ones but in tittan on my Alpinweiss, but the 403M's are really superb, pity they are 8.5! The 403M in 9.5 ET40 would be really top (for me)! Congratulations, one of the best F30, ever seen...
