    Need help confirming wheel fitment

    Hey guys, here is the fitment I plan on ordering lmk if you think this will work out without spacers and/or rolling fenders, I don't want to be worrying about rubbing when taking hard turns.

    Front: 18x9 with +31 offset with 255/35r18 tires

    Rear: 18x9.5 with +31 offset with 275/35r18 tire

    I had with no issues before

    Front: 20x9 with +35 offset with 245/30r20

    Rear: 20x10.5 with +45 offset with 295/25r20


    I'm feeling pretty good about the rear fitment, but it's the front I'm a little unsure of, I'm not sure if I should go +36 instead

    Do you have camber plates in the front? You're going to need between -1.5-2.0* to keep the fronts from rubbing. I'm currently running a 19x9 +30 with a 235/35 and it rubs on dips while turning, and that's with vorshlag camber plates running -1.5* camber.

    Damn, that's surprising, had no issues with my last setup didn't think this was much different. Why would I need aftermarket camber plates? OEM spec is between -1.3 to -1.8? I can't remember where I'm at now.

    OEM spec without M3 lower control arms is -.5* and is non adjustable per the manual. You can add M3 lower control arms and be near -.8-1.0. If you pull the strut mount pins and push the strut mount in, you can get near -1.0 without M3 lower arms, or near -1.5 WITH the M3 lower arms.

    On the offset, 5mm doesn't seem like much, but its actually quite a bit.

    I concur that 18x9 ET31 255/35r18 will most likely require camber. I'm 18x9 ET41 (soon to be ET38 or ET36) 255/35r18 Toyo Proxes R888 (tire sizes vary!) and I'm really close on the outside with pins out and M3 control arms (for -1.1* camber).

    Fronts will be fine with some negative camber work. Rears will need a fender roll if you plan on lowering your E92.

    Ended up ordering

    18x9 with ET36 for fronts

    18x9.5 with ET31 for rears

    I know rears will be good, my Vossen 20x10.5 were good with 295 tires and ET45 and really needed a 5mm spacer. So you figure losing 12.5 mm on wheel size plus 14 mm from more aggressive offset on new wheel, should be perfect. I'm thinking fronts will be good now too.

    Thanks guys, I probably woulda went with ET31 on fronts if I didn't post this, and probably would have been disappointed.

    I will post pics once wheels come in and are mounted, probably ~4 weeks.
