SAE team guys, and anyone else - suspension design software ?

started plugging stuff in … then found a tutorial for susprog3d…

and realized it said this:

You will need a registered copy of SusProg3D, version 4.70a (or later).
The demo version of SusProg3D cannot be used for this tutorial because it does not allow for changing the upright and wheel dimensions.

which keeps me from entering my knuckle measurements, and since i have 15" wheels, that will screw up the calculations also … fuck

anyone else have ideas ?
