Anyone try these with/without spacers on a F56 JCW? I'm trying to convince myself to get some aftermarkets wheels but I will not have spacers- can barely tolerate centering rings.
Machined silver might look cool on Moonwalk Grey with my chrome tidbits!

stance it out bro!!!

Seriously, you might need to bump it out 5mms or so. you won't even be able to tell the difference. I have 17s on B14 coils and needed to space the rear because they were rubbing the suspension.

Spacers and hub rings are the leading cause of Anxiety - in me at least. Why cant the factory use BBS out of the box or something like the Nismo 370Z wheels?

I have the RSe05 wheels and don't use or need spacers. If they had the machined finish in 17" I would have bought those instead of the gunmetal.

I did send out an email to Jerry @ NM Engineering and he said "I think 5mm spacers will be sufficient to clear the JCW brakes."

Almost ready to pull the trigger on these or the Vorsteiner V-FF 108's, both are going to need spacers. Decisions, decisions...

I dont understand why spacers cause you so much stress. They literally just go on the top hat of the brake rotor and you screw the lugs in.

Mainly because it's a reminder that it's not only non-factory but it also requires modifications to suit. Also, doesn't a spacer push the wheel off of the "top hat" that much more i.e. relying more on the lug nuts?
IMO in the 90's BMW started spec-ing nice looking BBS wheels, don't care much for the newer stuff out there. I think I'm just keeping my stock track wheels.

The lip on the wheel hub doesn't support the wheel loads. That is done by the clamping loads provided by the lug nuts. You can get to the point where a very large spacer would be dangerous (hence why the larger spacers like 25+mm are bolt on spacers) but a 5mm spacer? Zero issues.
