Spacers? 193m SQUARE 8.5x18ET37 255/35R18

drummr8 · 01-04-2020, 12:10 PM

Hey guys, I have an LCI Sedan with xdrive. I just installed ST coilovers and I'm putting a SQUARE set of 193m (msport) rears (8.5x18ET37 255/35R18) on the car. Will spacers be required to avoid suspension collisions? If so, what size? If not, what size could I use to improve looks without rubbing fenders?

Thanks, and sorry if this has been asked before. I searched but couldn't find my exact scenario.

Hi drummr8,

On an LCI E90 with ST Coilovers and a square 18x8.5" ET37 setup using 255/35 tires at all four corners, you will more than likely need a 5mm front spacer to clear the inner suspension components. Depending on what specific tires you are running, you might be able to get away with a spacer-less fitment but the clearances would be VERY close and not something I would recommend.

You could also run 5mm rear spacers as well to help with a slightly more flush fitment. Or even 12mm rear spacers to bring the rear wheels out to right around where a 18x9.5" ET35 (popular non-M E9X rear fitment) would sit. However, depending on ride height, there might be a very slight chance of rubbing on the outer fender with a 12mm.
