Using high roll centers (geometric anti-roll) can cause a jacking force that in the extreme, can roll the car (traction roll). This is why most independent suspension designs have a roll center well below the cg. This is the main problem with swing axle designs (Corvair, Beetle).
It is possible to have a high roll center with low jacking forces. Most beam axle designs accomplish this.
