ST Rear Anti-Swaybar BMW E28 E24

Looking to improve the handling of your vehicle? Our ST Anti-sway Bars are the ideal solution. By upgrading the anti-sway bars you reduce the amount of body roll and ensure improved handling while providing better traction. ST Anti-sway Bars improve the driving dynamics of your vehicle and complete your suspension upgrade. Our ST Anti-sway Bars are made of cold-formed heavy duty aircraft steel. The reduction in the wheel load differential between the outer and inner wheel in a curve will be immediately noticeable. Depending on the vehicle, some of our ST Anti-sway Bars are adjustable to give you the freedom to fine tune the force and further improve your vehicle's lateral stability and cornering grip. Our high performance ST Anti-sway Bars go through multiple quenching and tempering processes along with a final epoxy coating to maximize the protection from extreme weather and road debris. Not only do they look good, they are also built to last.

Additional Information

Due to the improved lateral control, reduced tendency for body roll, and the minimized load differences between the outside and inside the wheel in a turn; you will feel more direct handling when going into curves or with fast load changes.
