First off, are there any more pics of the process of lowering the car that low? I'd like to see the work if he has pictures and is willing to share.
Second, does anybody know anything about the BMW and Mercedes dynamic ride height adjustment systems? I've searched all over the net for information on how they work, but have always come up with nothing. I wonder if you could find a wrecked BMW and stip the mechanicals from it to do something similar with a custom 'Cuda.
At slower-than-highway speeds, the car would be raised up a few extra inches, but when you hit high speeds it lowers like the pictures above. If anybody has the skills to make the car that low with that much fabrication, I bet dynamic ride adjustment wouldn't be that much harder.
When I get my e-body, I plan to look into it. I'd love to have an auto lowering car. You might even be able to rig it to work on a switch too. Up down or auto adjusting based on your preference. The best of both worlds. A car with low clearance for awesome cornering but high clearance for parking and getting into sloped driveways without scraping the valance panel.
