So far, I don't think anyone has mentioned the #1 (IMHO) cause of Solo 2
rollovers, and why it is such a problem.
When the suspension hits the bump stops, the instantaneous roll center
changes very suddenly, from somewhere along the vehicle's centerline, to the
contact patch of the outside wheel with the ground. This suddenly increases
the center of gravity's leverage over the roll center by a huge amount, like
doubling or tripling the lever arm. This is why cars tend to "pop up" onto 2
wheels suddenly, sometimes going over.
While increased rebound damping can keep the bouncing down and might help
keep the car off the bump stops, compression damping helps right from the
start...
