The 245/275 setup on the F30 works out really nicely. It's also nice knowing you've got a lot of tire between the wheel and the road.
Have any pics with the spacers installed or are you waiting for coilovers? I think Bilsteins are available by now, could be wrong though.
edit: Oh and I'm glad I saw that the sport trim can be added to a no-line car, I was just asking myself this question 30min ago!
