I'm wondering if there's some repository for how to purchase and size BBS 3 piece wheels and have seen a lot of confusing verbiage in the forums on this topic. How do I know what center I need and what lips and barrels I need for a specific wheel size and offset?

I found a good article in the Bimmer forums along the lines of what I'm looking for but I'm surprised there's nothing like that on Rennlist:

Can somebody share how to choose these things? I'm in the market for E88s right now trying to size these appropriately.

Edit:

Interesting in that I am also looking to find/source 18" BBS wheels (specifically LM for NB fitment).

These are like finding the proverbial needle in the haystack!

Any insight as to sourcing parts to build a set?

You can call Eric above or check out Bob Woodman's website (just google his name). He has halves, lips and centers priced out.

Actually spoke with the folks at the John Woodman place earlier today. They only offer BBS parts for Motorsport application (E88 type) Per the person I spoke with, the Motorsport wheels are not deemed street qualified and are easily damaged compared to street wheels (LM Type).

SupremePower

We have many street cars on the BBS Motorsport wheels. While it holds true the LM 2piece forged wheels are stronger, we have not had any issues with the BBS Motorsport 3piece wheels.

BBS Motorsport now use the thickest barrel so we dont have the issues as when they used to use the thinner outers.

Interesting - thanks for sharing the experience.
