Is anyone using this software at the moment. I'd be interested in purchasing it in the future (money permitting) if it is good.

download the free version (scroll down the page a bit)

what i can say is it looks "comprehensive".

Hey,

I've used this software to design and build a small race car (FSAE car with double wishbone/pushrod suspension).
It doesn't do dynamic analysis type of stuff (you will need AdamsCar or something) but it is very useful if you know what roll centres, camber curves, steering camber, bump steer etc that you want.
Basically it is comprehensive for geometry design. You can also design for spring and roll rates by inputting spring/ARB dimensions
which is handy.


I did some verification after the car was built (camber curves, bump steer etc) and it was pretty close, basically any small difference could be attributed to manufacturing error. I also checked the result of the program against CAD and it was the same.

It was well worth the money for me, also the software is regularly updated. If you find a bug or need another type of suspension added you can contact the maker and they will fix it pretty quickly!



I'd really like to do an analysis of a sprinter (ae86) or KE70/71 corolla. If someone wants to measure up hardpoints I could make a model of it and see what improvements can be made. Unfortunately I don't have one of these cars at the moment to measure but may get around to getting some dimensions from a wrecker or something.

ill do it, send me the list.

or what about just chassis repair data?

saves me learning the program maybe too.. only want to tune 1 little thing.

i think i have it worked out anyway, but yeah.
