I've searched but am still unclear. Before I order can someone confirm whether OEM 17 inch 42s will clear the front rotor?
Thanks, Dan.

I saw that thread but it is unclear to me whether the 42s discussed were 17 or 18 inchers. I need 17's for my snows as I have an apparently unfixable bent rim (of different type)....

Now that I read more into it, it looks like they are referencing the 18s. Do you know the offsets of the 17s off hand?

Offset is the same on E39 17" Style 42's, ET20.

anyone have any idea if a spacer will help any or is it the entire barrel of the rim that doesn't clear the M5 rotors?

17" have ET26 for the 9" rear

Good luck finding a 17x9" rear. I've never seen one in person.

unless RealOem is incorrectly cataloged or not up to date - then you should be able to get them from the Dealer, but it's definitely not ideal if you own an M5 when for an est. $200 more (on top of the $650-690 per rim) you can pic up the 18" Set

I don't know that a spacer would help much plus an offset of 20 is what is spec'd for the fronts on our chassis. Anyone else? I can't believe I'll have to be the first in 10 years to find out...

I have a brand new set of staggered 18" I'd sell for $1400.

17x9 in a Style 42 isn't all that rare.
Here's a staggered set on my 528.

I still haven't seen a set in person. ;)

DHoang,
Can you stick a tape measure in your front spoke and read off the distance from the face of the caliper to the nearest inside of one of the spokes? Maybe I can extrapolate fron there....

I've got brand new pads all around, and as you may already know, my calipers aren't as robust as the M5.
The measurements I got clears the outer surface of my calipers by 1.375" , for both the front & back. Not using any spacers. HTH...

The data here specifies that they are not suitable for the M5.
i think that chart doesn't correctly exprapolate interchangeability across the board, as I see lack of information with the data.
Take for instance the style 66 on that website, a 17" wheel BMW spec'd just for the E39 540i M-Sport. Yet, on that website, it only shows this wheel fitting the E39 M5 only. In reality, this wheel was never on the M5, yet it will fit just about EVERY non-M5 E39 ever made. ouich

The information on style 66 on that site, here, shows that the 8x17 is for the M5 with winter tyres and that the 8x17 and 9x17 are for E39's except the M5 and Touring.

Ok, the inner profile of spokes is shaped in a way that the wheel shouldn't need spacers to clear the caliper. I just need to measure the inner diameter of the 17s. About 15.75" is needed in diameter to clear the lateral edge of the caliper. If I move on this I'll post an update in order to solve this once and for all....
