Thanks guys for your comments. I’ll do my best to answer your questions.
4WheelDrift, Calculating the location of the CG would be an enormous task, it’s much easier to measure it. Finding the front to rear and side to side location is easy just find the point at which the chassis balances. Finding the point where it lies from the bottom of the chassis is more difficult. I would think some sort of jig that would allow you to hold the car and find the point when the chassis hangs perpendicular to the ground would be the easiest solution.
Mark506, It’s looks like the program crashed or exited prematurely. The only suggestion I have is try again. Others seem to install it OK. It make take a while for the Microsoft Apps to install so you may have to be patient. I know it took a while when I installed it on my laptop with Vista.
Fatbear, Yeh I didn’t include different tire width option for front and rear. I don’t think it should make a huge difference though. Just make two models, one with each tire width and see what the difference is. I'll keep this in mind for future upgrades.
As far as setup is concerned in very simple terms the lower the roll centre the more grip and the more camber gain the more grip. Obviuosly there are limits to how much grip you need and sometimes you need to go the other way and reduce grip. The best advice would be to get a good setup book like the XXXMain Setup Guide and read it, then read it again, and again. Well you get the idea. You can find the book here:
