I ordered some Forgestar CF5s for my 2007 Shelby GT500 in brushed titanium. I went with 19” x 9.5” in front and 19” x 11” in the rear. While I believe the 19” wheel size is perfect for the S197 body style it really limits your tire choices over 300mm wide. I plan to run a Nitto Invo 325/30/19 in the rear. Does anyone have a picture of that tire on a S197 or better yet a GT500? Thanks!
