Are there any 18 or 17 inch wheels that will clear lowered coilovers and BBK's?
 

As per the title, any wheel that fit that criteria without spacers? I LOATHE spacers. I would have to change my nice R105 wheels then :sad:

Depends on the size of the BBK rotors, size of the caliper, size of shock body, size of the wheel, and offset of the wheel.

I found this thread, but I'm not sure if it will help you or not in figuring out what rims are compatible: https://www.northamericanmotoring.co...w-jcw-bbk.html.

Sorry for not being more descriptive.

I have the R53 BBK, so it's not as big as the R56 version. My old R95 wheels cleared those by quite a margin. So 17 or 18 diameter wise will be fine.

It's the ET's that are the tricky part figuring out :(

Well, to my best knowledge, R53 JCW brakes and R56 OEM brakes are the same size. Having said that, you should be able to use any 16" or larger rim with a 38-50mm ET. The wheel shop you go to should provide a JCW brake option for spec selections. I'm sure you've seen this link before: https://www.northamericanmotoring.co...re-weight.html. Use the OE links as guides to pick your ET. Looks like alot of them have an ET of 45.
