IMO its the law for you to get some 4x108 (hom ford) to 5x114.3 (jap) conversion spacers made up (i know a company), and run a set of ET30 9.5x18 Rota GTRs running some mega stretched tyres under some mega flared standard arches.

End result would be a lil bit like this, but on a Sierra, of course



Proper sexual, low offset wide rims under mega flared arches are the way to go on any motor IMO
