I have for sale a solitary front wishbone bush for the Z4 (and other BMWs). It would be unusual to want just one, since they are sold as a pair but perhaps you might find yourself in the same situation that I did, which was this.
When I had sold my Z4 MC I bought an Alpina B3. Prior to sale it was MOTd and failed on a lower wishbone bush, so needed replacing, which the owner did before I picked it up. Although he bought two bushes, he wouldn't give me the spare, so once I got it home I replaced the one on the other side. As a result I have spare one.
Here's the link to Eurocarparts showing the item as per Z4 2.0 but I believe it's right for all non M Z4s (E86)

Clearly it also fits an Alpina B3 if you've got one of those tucked up at home too.
