Winter Set up 18" Style 209's Not Fitting on my 2010 4.8???

[Riggi24]

Just purchased these wheels for my winter set up from a local guy here in Boston: 18" Style 209 OEM wheels, powdercoated on Dunlop Grandtrek with TPMs.

Had my local shop go to mount them today and they will not fit around my calipers (rim was not clearing the backplate of the brake caliper)??

I have a 2010 4.8 sport pkg with 20" staggered 214's and after a lot of thought I opted to go with 18" wheels for winter rather than keep the 214s with Pirelli Ice & Snow. I know MANY people on this forum who have the 4.8 with full sport pkg & 20" y-spokes have put the 18" OEM wheels on for winter set up.

Please provide me feedback on this
