looking at a set of rims right now that would likely push the limits of offset and i'm wondering if anyone is running anything this aggressive. i've looked at several threads that tell me this will be close, but i also don't want to run a stretched tire to make this work. i'm hoping for a 275 or 285 rear tire on a 10" rim. i'll likely run Conti Extreme DW, which have a round profile and will aid in getting the tire inside the fenders.
i know 2phast has said he is running/has run 18x9 all around with a final offset of ET15 (ET35 + 20mm spacers) which would indicate the fronts would likely work, but the rears would be tight. i've also run across a wheel site that showed a 18" BBS rim for the 500E that was a 10" rear with ET20 (3 mils more than i'm looking at).
specs of the rims are below. would like to hear from anyone running anything close and whether there were/are any clearance issues.
8.5" front ET21
10" rear ET23
