I have a minor update on the car. I did some measuring and it looks like the rear will be about 6" wider than stock. This will make it the same width as the front (outside of headlights) and 5" narrower than at the doors. It will still retain general flow of the car but will be closer to the Vox renderings visually. I will post some pictures from my phone in a few minutes.
When I first ordered my wheels I was a little conservative and could have gone with a larger backspacing on the rear. It has driven me crazy and this past few weeks I narrowed the 8.8 Ford to fit the way I want. In the process I converted the rear end to have 9" ford ends thus eliminating the C-clip axles. I think the fixed caliper Wilwood brakes will work better and I feel a whole lot better with that setup. The narrowing really wasn't that hard to do. I purchased a jig on Ebay and went to town. I forgot to take any picutes but it looks about the same as it did before. The tires fit right inside the fenders now and will reduce any kind of flare that may have been needed. Now a simple fender lip like stock will work fine.
