Hi all,
I have purchase oem style 124 e60 sport pkg wheel, 18x8j and 18x9j with 245/40/18 at front and 278/35/18 at rear
Two questions. Does my 03 e39 able to run this size of tire without rubbing anything?
I need to know the bore center size of the e39 hub or original BBS RS 740 wheels. Please help. Thanks in advance.

I need to know the bore center size of the e39

E39 = 74.1mm. Other chassis = 72.56mm.

you need a hub ring, find out the offset as well

Thanks for the replies guys.
What hub ring do I need? Why do I need one?

The new wheel offset front is IS 20, the rear is IS 32.
My old wheel offset front and rear are IS 20.

Can I use the rear wheel with IS 20 offset without the spacer?

well the staggered fitment for a stock e39 is 23-25mm for the rear, i think you may rub the rear caliper with the rears...not to sure. Well measure the center bore of the wheels and subtract from 74.1mm(which is the e39's) and that is what you need...

Hi, thanks.
"That's what you need..." what do I need? spacer?
the new wheel center bore is small than the old wheel.
I'm plan to bore the center out. One thing I'm concern about the offset and rubing.

a 5mm spacer spacer should help you out in the rear

As I know, for e39, the minimum is 10mm spacer, and it's very sensitive for e39 to use spacer, it will get shimmy.
