About this swaybar
The Whiteline BMR12Z rear sway bar is engineered for precision and balance and maintains optimal suspension geometry under load, the perfect, complete upgrade. Sway bars are principally designed to reduce body roll, spreading lateral loads more evenly across the tyres for more cornering grip and better outright performance. Whiteline calls it the best dollar-for-dollar handling improvement you can make to your vehicle.
Engineered to 'Activate More Grip', sway bars are principally designed to reduce body roll or sway. By reducing body roll, lateral loads are spread more evenly across the tyres thereby increasing cornering grip and improving outright performance. This Whiteline 16mm 3 point adjustable sway bar = more grip = better handling = outright performance - it's the best dollar-for-dollar handling improvement you can make to your vehicle. In fact, benefits extend to improvements in handling, safety and tyre wear without affecting ride quality or comfort.
