Will this work?

Front: SM10 ET30 - 18x9 235/40/R18
Rear: SM10 ET30 - 18x9 265/35/R18

The official recommendation for an agressive staggered wheel setup with no mods here is:
Front: SM10 ET30 - 18x9 235/40/18
Rear: SM10 ET35 - 18x9.5 265/45/18

However, the rears (18x9.5) have been "pending production" for a while now.

Please let me know if I can sub the 18x9.5 ET35s with the 18x9 ET30s, and not have to make any modifications to the stock brakes/suspension/fenders?

I want to go with the Satin Black wheels on a Titanium Silver e90, for the curious ones.

Thanks much!

I went with this one, in SM-10 ET30 Satin Black (my car's Titanium Silver):

E9X 3-Series Performance 18” Square Wheel Package

With these tyres:

Michelin Pilot Sport 4S 255/35-18 Max Performance Summer Tire

I'm pretty confident that this setup will work with my LCI xDrive.

You chose well. Square setup makes a lot more sense than staggered. These cars already tend toward understeer. This is the way.

Post some pics once they're on.

I appreciate the feedback, thanks much!

I owe all credit to this comprehensive documentation provided by the Apex Race Parts team, I must say!!! Also, all the docs here.

That stuff is treasure, right there!!!



I will post pics asap!

im running the SMs 18x9 +30 all around with 255/35. no rubbing. no spacers. bc racing coilovers. stance is leveled. 0 gap in front. tucking tread in the rear.

im have a set of 5mm spacers for the front and 12s for the rear. will also be raising the rear up to 0 gap to match the front.

I also have BC Coilovers. Do you think running the 5mm spacers is a necessity? or could you make the same fitment work without it?

I've been running with 0 spacers since I put my coils on and that was back in April. I haven't thrown on the spacers yet. They've just been chilling. Waiting for it to get warmer before I dial down the fitment. I think I can even go 15mms in the rear but we'll see. Baby steps lol. I was originally going to go 10 or 12mms in the front but decided to go this route. If I can go more I can just shift everything forward. Technically if I had more money I would just leave this set for snow and try to fit 18x10 +25 all around🤷🏻
