Very nice brother, congrats!! I've also got a BS sports. A must do is get blacklines & debadge. I guarantee you won't regret it! The rear would like 100X wider and so much cleaner. And if possible get the rear m lip!
Note for some people who are looking at getting an e90/e92 and want to uprgrade wheels.
When i went to purchase my e90 it had 17" sport on them and there was a model with the 18" on them and I told them i wanted a swap and they told me no way! And advised that i would have to fork out $1800 if i wanted to do that, but i didn't think it was worth it and insisted them if they didn't want to swap it then i won't be buying the car. 5 minutes later, papers were being signed.
