Those wheels are the original 17" SV6 wheels for series II V2, same as VY SS ute. There were 2 x optional wheels as well. As far as I know the export GTO had the CV8 18" rims but in gloss not satin like we got here. I bought 2 x sets of them for my CV8 as they are easier to clean. They even came with Pontiac centre caps.
