Interlagos in São Paulo, Brazil, is already confirmed as one of the two venues for Round 8 on Wednesday night.
The second stop for the night was left to a BP fan poll, with Spa, Phillip Island, Michigan and Watkins Glen the four nominated options.
In the first semi-final, it was Phillip Island that got the nod over Watkins Glen by winning 66 per cent of the vote.
The second semi was a fraction closer with Michigan drawing 37 per cent of votes on the back of the oval success that was Charlotte last week.
It was not enough to topple Spa, however, which played host to close racing in Round 5 of the competition.
That leaves the Belgian and Aussie tracks as the last two standing, with a vote currently live on the Supercars Facebook page – Phillip Island holding a slender lead at the time of writing.
The winning circuit will be announced at midday on Wednesday.
All up, more than 15,000 votes have been cast to date.
