And I also took a look at the free model jeep as one of the threads mentioned it could help, but I couldn’t make much sense of any of it. Also, in the first post OseDay had commented with a formula which used hookes law in a second order problem (which I don’t really understand that well). Also I don’t really understand what you meant when you said use a inverse square function at the end of your reply and how I could apply it to my solution. This is my first time really dealing with cars so you’ll have to bear with me if I don’t understand some of the terms your using.
