There for a while I was trying to design something similar. Wanted to narrow it so the wheels are tucked in, or flare the fenders a bit like GM did on the Monte they built. Also I made the front frame so it wasn't so straight, thought this would provide some crush zone if ever in a front end crash. Yea I know, lower front crossmember isn't attached. Thought maybe if I ever bought a front cradle I would incorporate it, but have it narrowed a little bit.
