• DIY-friendly bolt-on installation kit with all necessary hardware included

Construction & Design:

The Whiteline 18mm Rear Sway Bar is crafted from premium spring steel, chosen for its excellent strength-to-weight ratio and fatigue resistance. The bar undergoes a precision manufacturing process to ensure consistent performance and durability under demanding driving conditions. A protective powder-coated finish guards against corrosion, extending the life of the component even in harsh environments.

High-quality polyurethane bushes replace the factory rubber mounts, offering reduced deflection and improved feedback without transmitting excessive noise or vibration. The adjustable lever arms are engineered to provide a smooth, reliable mechanism for altering sway bar stiffness, allowing drivers to tailor handling characteristics to their preferences or specific driving scenarios.

Performance & Sound

By increasing rear roll stiffness, this sway bar significantly enhances cornering stability and grip, allowing drivers to carry more speed through bends with greater confidence. The reduction in body roll also contributes to a more connected and responsive driving experience. While the sway bar does not directly affect engine sound, the improved chassis control can make spirited driving more engaging and enjoyable.
