Found another set of wheels but just need to know if these specs will work on a 2004 530i

20x10.5 all around

Offset 30mm

Back spacing 6.93"

Center ore 73.1

If anyone can chime in that would be great!

I don't see the fronts fitting. Rears shouldn't be a problem.
Have some fun with this. http://www.rimsntires.com/specs.jsp

That website is pretty cool.....I think the front may fit with a smaller tire maybe 235 35 20? I wish I knew before I consider buying

widest front width I have seen on an e60 is 9.5"

10.5 and 30 offset wont clear the strut.
