BZ5 Rear Anti-Roll Bar Set (0.7, 0.8mm)

An anti-roll bar (roll bar, anti-sway bar, sway bar, stabilizer bar) is an suspension part that helps to reduce the body roll of car during fast cornering or bumps.
It links left and right wheels to a torsion spring rod and lever arms for anchors. This increases the suspension's roll stiffness—its resistance to roll in corners and lower ride height of the car during fast turns.
