Sizes: see table below
- An anti-roll bar links left and right wheels so the car rolls less. Stiffening one end reduces that end's grip: a thicker front bar gives less front traction and less off-power steering but quicker response; a thicker rear bar gives less rear traction and more on-power steering (Tekno).
- Thicker bars at either end reduce chassis roll (CompetitionX).
