One other thing I was thinking about, which would take quite a bit of measuring, was to actually integrate the front end of a newer Charger into the frame. Not sure if it would fit in my car but did you think about it in yours at all? The reason being, the suspension and handling is essentially Mercedes, it handles amazing, and you could simply bolt on higher end brakes (like off a SRT8) easily. Also, if you need replacement parts or pads, you could get them anywhere. Just a thought I've been playing with.
