BMW 6 Series (E64) Sway Bars
First and foremost, BMW 6 Series (E64) sway bars are designed as safety features, implemented automatically when high levels of torsion increase a vehicle’s rollover risk. The greater the stiffness of the BMW 6 Series (E64) sway bar is, the greater the resulting amount of force required to induce a rollover is. SUVs, trucks, and other larger vehicles are especially prone to these rollover forces, and so it’s more critical for owners of these types of vehicles to install effective sway bars to prevent these unfortunate outcomes.
