Suspension Geometry Design Program

OK, probably not of much interest to most of you, but if you're thinking of building your own real car, this is pretty cool. Back in the dim recesses of time, I used to do this stuff with 2-dimensional models made from balsa, pins and string. Reasonably accurate, but incapable of analyzing small changes quickly, and only worked in two dimensions. This is freaking magic compared to that, and it's cheap. Runs under XP, 7, or Vista.

Similar stuff is available for rear suspension, chassis layout , etc.

That is neat.
