ST Suspensions rear anti-sway bar for the 2008-2016 Audi A4 / S4 / A5 / S5 (B8) in 2WD and Quattro. Cold-formed from heavy-duty spring steel and finished with a durable epoxy/powder coating for long-term corrosion and road-debris protection. Reducing the wheel-load difference between the inside and outside rear tires cuts body roll and sharpens rotation for flatter cornering and more consistent traction. Includes composite bushings and mounting hardware; many applications offer multiple adjustment positions to dial out under- or oversteer.
