widest wheel

275/40/17 on our Leadfoot Rally Duster. 17x9 rim with (I believe) 5.97" of back space. Moved the springs inboard .80" with the MP hanger kit, and used a '67 B-body 8.75" housing which was a little bit wider than the a-body 8 1/4" we took out.

Oh we painted it flat black--sorry off topic for this thread, I know!
