Roll center

Finding the roll center of a MacPherson strut

The roll center of a vehicle is the notional point at which the cornering forces in the suspension are reacted to the vehicle body.

There are two definitions of roll center. The most commonly used is the geometric (or kinematic) roll center, whereas the Society of Automotive Engineers uses a force-based definition.[1]
