Be careful when using demo versions of software. Nothing is free. Sometimes the company will disable features or handicap the software. The demos are for showing how the software works, not for 100 percent actual calculations. I input all the same numbers in my purchased version and it comes up with a roll center height of 8 inches. Right where your panhard bar is mounted.
