Thanks for posting pics. Helped me decide to go with the Bathurst too, but in 18x8 all around.
Just an FYI, most of the online shops will try to sell you the 5x114.3 as the right fitment for the ATS. Wasted a good part of the day trying to get one of the online stores to get the 5x115s. It doesn't help that TSW's fitment guide also only shows 5x114.3 for the ATS.
Decided to try my local America's Tire and they were able to get in touch with TSW as I waited. TSW confirmed they have 5x115 available and can ship them in a couple of days. America's Tire also had these for ~$20 less per wheel than the Online Stores which was a pleasant surprise.
