gotta go with the others on stripe test 4. I like how it widens out. As for test 5, personally not so keen on it as it doesn't follow the body line at the front of the car that well to my eye, but could be tuned a bit and I would like it too.
As for the wheels, try the ones you have first. I like 'em. I am apparently one of the few not into the monster wheel thing (up to 18" looks good on the Muscle Cars IMO) and I think those will be a nice "period" touch. I like Forgelines too of course, as long as it is kept at a reasonable 18" maximum IMO.
Like the car nonetheless
