Body Roll

It is caused by the centre of gravity being above the roll centre. Anti-roll bars, stiffer springs and lower centres of gravity reduce it. Tall vehicles roll more. Sports cars and SUVs with active suspension can counteract body roll electronically or hydraulically. Some roll is normal and gives the driver feedback about cornering forces.

Cornering force pushes the body outward and compresses the outer springs.

Increased roll can point to worn shock absorbers or broken anti-roll bar links. Heavy roof loads increase roll.
