BBS RS047 Fitment Question

[papag1234]

I have a set of BBS RS 047's (4x100) that I am refinishing.
15x7 et38

I drive a 1992 318i cab

I am looking at Black Forest Industries for wider lips. I know the offset will change, but I don't know how to accurately account for it. I'm also looking for suggestions for the sizes of the lips. I was thinking about running staggered 15x8.5 and 15x9.

What else do I need to take into account. Will I have to run spacers with these wheels? I really want to do this once and not mess up/leave anything out of the order!

Any help is greatly appreciated. This is my first time dabbling in multipiece wheels

Have you fitted them on your e30? You'll need spacers if the inner barrel/tire rubs against the strut tube.

Awesome. Thank you for that Mike! I have not yet fitted them on the car. I have them taken apart. Do you mind me asking how you know the specs for the wheels and how you calculated the offsets?

I think after reviewing the offsets you posted, it looks like I'm definitely going to need spacers to clear the strut. It's looking like running 1.5" and 2.0" lips would be better suited
