I found out something today I didn't know. Did a search on here and didn't find anything so I thought I'd post it.

I bought wheels from an e60 for my touring. I assumed the center bore was the same as an e39 so I also bought the hubcentric rings. Turns out with the e60 they went back down to the 72.6mm hub so e60 wheels bolt right on.

This should mean more wheel choices available in the correct offset and center bore for the e34 as more manufactures start making e60 specific wheels.
