I don't think you'll have a problem with rubbing.

I don't know the difference between the m sport and sport suspension in the e60 but visually I think it looks much better in the pro kit than the sportline kit.

My springs have been in about a month now and have settled down nicely, the ride is absolutely outstanding, I'm very happy with the choice I made

Here's a photo of colms e60 on a pro kit vs another image I found of a car on sport lines
