I swear I have read no less then 60 threads on this topic but i still dont feel confident I 100% understand. My question is will this setup work on my 06 530xi?

Its the right bolt pattern, i know 20's will work and from what i understand as long as the offset is 38 or higher they should be good?

I appreciate the help!

So standard wheel size on xi are 18x8 ET:43.



According to the calculator comparing stock to 20"x9" Offset 40....

The rims will stick out an addition 16mm. Yes, the offset is close, but the 20 inch rims are one inch wider than stock.




I run a pretty aggressive offset on my car and I stick out 10mm at the rears... but I bottom out when I go over bumps even with fenders rolled. Plus if you are sticking out 16mm in the front, I don't even think you could do full turns without rubbing...unless your car sits really high

 

Awsome, thanks for the link. That clears up my confusion regarding wheel width and offset. Thanks
