AST Lowering Springs For BMW 5 535/525D/530D/535D with airsuspension HA - Incl. Lowering Links for the rear 06/2010-03/2017, Front 30 , Rear 0-30

The AST Lowering Springs are precision-engineered components designed to enhance the driving dynamics of your BMW 5 Series (models 535/525D/530D/535D with air suspension, years 06/2010-03/2017). Manufactured using state-of-the-art Wafios coiling machines, these springs are cold-coiled to ensure superior durability and consistent performance. This meticulous production process guarantees a product that meets the highest industry standards, providing a reliable upgrade over the original equipment manufacturer (OEM) springs.

These lowering springs effectively reduce the vehicle’s center of gravity, which translates into improved handling and stability without significantly compromising ride comfort. The progressive spring design offers a balanced approach, allowing drivers to experience enhanced cornering and road grip while maintaining the familiar comfort level associated with OEM suspension setups. This makes the AST springs an excellent choice for those seeking performance improvements without sacrificing everyday usability.

Specifically developed for the BMW 5 Series models equipped with air suspension, the set includes front springs that lower the vehicle by approximately 30 mm and adjustable rear lowering links that provide a range of 0 to 30 mm adjustment. This flexibility allows for precise tuning of the rear ride height to suit individual preferences and driving conditions. The rear lowering links facilitate fine adjustments, where each 1 mm change in the link length corresponds to an approximate 5 mm change in vehicle height, enabling tailored suspension settings.

The minimum recommended ride height at the rear is approximately 355 mm, measured from the center of the wheel to the wheel arch. Maintaining this minimum height is crucial to preserving ride quality and preventing adverse effects on suspension performance. It is important to note that excessive lowering can reduce the air volume in the suspension system, potentially triggering error codes in the vehicle’s onboard computer. Therefore, careful adjustment within the specified parameters is advised to ensure optimal functionality and safety.

AST stands behind the quality of these lowering springs with a lifetime warranty against breaking, underscoring their commitment to product reliability and customer satisfaction. Please note that these springs are not suitable for four-wheel-drive (4WD) vehicles. Additionally, for cars that already feature standard lowering, the effective lowering achieved by this kit will be reduced by the amount of the existing lowering.
