Trying to convert my old PM file to an ultra chassis and I am running into a problem. I follow the tutorial in the introduction PDF and the car loads but the wheels just fly off, the car flips upside down and eventually it will really wig out and lock the game up. In an attempt to see where I went wrong I snagged the Skip Barber example and plugged that one into my mod, it worked, although the suspension collapsed... I don't think the Skippy was meant for 18" of suspension travel. So it worked, and the wheels stayed on, great success. I figured I would copy the constraints from that file over to my ultra chassis since the wheels actually stayed on. Same problem as before, wheels flew off. Any ideas where I went wrong? Here's the wheel flying ultra chassis INI. http://www.mediafire.com/view/s5dsxy8fqtbt795/carachassis.ini
