I like the stance. It's about perfect. It's really what I wanted when building mine, but I didn't want to go through all the additional necessary mods to get it there. As far as the windshield goes, I thought I wanted a low, laid back one on mine until I mocked it up. It just didn't agree with the direction the build was inevitably going. I believe if you mock up a few different options, the car will tell you which is best. Based on what I see, you have a good eye, so I'm confident you'll do the right thing
I know that it's all cosmetic now, but try to plan ahead for driveabilty and comfort also. A low windshield may look cool, but how will it be with the wind hitting you almost directly in the face? How low will you be sitting? I mocked up a few and landed on a 13" vertical. After driving it, I can't imagine it any shorter based on the wind I get now. But I also plan on driving the crap out of it, so that's important to me. Jim's car is very low and looks awesome to me with a low, laid back windshield. That same one did not look good to me on my car. Jim, how is the wind in your car? Just food for thought.
