BMW M4 Sway Bars - Front - Whiteline - 30mm Adjustable - `15-`20. A direct-fit front sway bar designed for BMW M4 models from 2015–2020, offering tunable roll stiffness to improve handling precision and cornering balance.

This Whiteline 30mm adjustable sway bar is engineered to "Activate More Grip" by reducing body roll and distributing lateral loads more evenly across the tires. The three-position adjustability lets you dial in front-end stiffness to match street, track, or mixed driving, improving turn-in response and predictable balance without sacrificing everyday ride comfort. Constructed for durability and precise fitment, this sway bar is a practical upgrade for enthusiasts looking to refine handling dynamics and reduce uneven tire wear caused by excessive roll.
