Arc-8 18x9 ET30 on E92 LCI xDrive on KWv1

starbuck · 01-02-2019, 04:03 PM

Hoping to find anyone who is running this setup. I just ordered Arc8 18x9 ET 30 in bronze. I went with these wheels as they are concave while the 18x8.5 ET38 is flat. The KW/ST are known to be a bit wider creating some tight fitment.

I will be running a square setup and been back and forth between 235/40R18 or 255/35R18. Im dropped on KWv1s and do not want to rub obviously. I am open to adding a 5mm spacer up front and/or adjusting the ride height a bit.

If going with 235/40 I was going to go with a wider 235 like the Michelin PS4S (unless someone has a different reco). Vice versa if going with with a 255 I would like to find the narrowest option (not sure which brand/model would apply).

Anyone else running these configs on the same car (xdrive on KWv1) ?? Any help would be appreciated as I am a bit concerend that I have purchased these wheels that may not have a way of fitting on my car without removing my KW or restoring to almost stock AWD ride height.

Thanks,

I had 18x9et30 ARC-8s with 235/40/18 MPSS on my non-x E92, also lowered on KW coilovers. Up front, I about 1mm of inner clearance and had visible tire marks on the suspension, however the tires didn't show any wear and I never noticed any rubbing. I recommend trying the wheels first and then buying a small spacer if you think it's needed.

I'm not sure if E92 x-drive has different outer clearance than non-x though, I've only owned RWD E92s.

Edit: found the pic of my inner clearance, I would embed it but the image is pretty big:
