i think they will go very well with your color. do they still have these sizes available? i think the 19x10.5's in ET27 sold out in gunmetal.
19x9 ET32
19x10.5 ET27
those would be pretty good. i'd probably run 10mm spacers on the rear though to make it ET17 and run stock tire sizes (245/40/19 & 275/35/19).
GL!
