Hi guys!

I own a BMW E60 sitting on 20" M5 replica wheels, lowered with Eibach springs.

The wheels in the front fit perfectly in their arches. The back is a whole different story.
On the back it looks like the wheels could use ~20mm spacers to get them aligned with the fenders.

Although, I don't know if I can just put them on there, because I've been reading about getting weird ET-values etc.

What do you guys recommend?

Would need to know ET of wheels before being able to answer. Try and find out.

 

i put 10mm on my stock wheels front def looks like it can take 15 and rear 20

 

I also want some spacers, i found H&R spacers 15 mm \ per wheel, 30 mm \ per achse (german word, sorry but i don't know the english term).
I have OEM 18's M with 245/40/18 and ET20 (i guess).

I think that this is the safest choice for "not rubbing".

Get a straight edge and a tape measure better yet a grade school ruler, measure your distance keeping in mind the wheel travel over bumps.
You should be able to get an idea of a acceptable spacer size... The interwebz lie.
