M37 Wheel offsets... winter wheel clearance issues

[SitDown]

Hey all - - just traded in our 07 M35Sport, for a 13 M37xS. What is the ideal offset on the M37s?

Hoped to reuse my winter wheel set from the 07, but found some caliper clearance issues. can any 18" guys chime in? Id like to reuse my tires, and get new wheels. I believe my old set of ASA GT1s were 18x8 ET 48. Using tire rack i see wheels in 35 offset that are compatible, and would like to get a wider stance in the process.

Any sizing guidance would be appreciated, ASA GT5s might be a good look if these fit(18x8 et35). Expecting snow today, so guess ill see how the AWD & summer 20" tires fair...

Thanks
