The AST Lowering Springs are engineered to provide a refined balance between enhanced vehicle dynamics and maintained ride comfort. Manufactured using advanced cold-coiling technology on state-of-the-art Wafios coiling machines, these springs ensure superior quality and durability. Designed specifically for the BMW 5 Series 525D/530D models equipped with air suspension (rear axle), covering production years from 06/2004 to 05/2010, this set includes lowering links for the rear suspension to optimize fitment and performance.
By lowering the vehicle’s center of gravity, the AST springs contribute to improved handling characteristics, enhanced cornering stability, and a more responsive driving experience. Despite the reduction in ride height, these springs maintain a level of comfort comparable to the original OEM springs, making them suitable for both daily driving and spirited performance use. The progressive spring design adapts to varying driving conditions, providing a smooth transition between comfort and sportiness.
Each set is meticulously crafted from premium materials, ensuring long-lasting reliability and resistance to fatigue. The product is backed by a lifetime warranty against breaking, reflecting the confidence in its manufacturing standards and material integrity. Installation is facilitated by the inclusion of adjustable lowering links for the rear, allowing precise adjustment of the rear ride height within the specified range.
These lowering springs are not compatible with four-wheel-drive (4WD) vehicles. Additionally, for vehicles that already have a standard lowering, the effective lowering height will be reduced by the amount of the existing lowering. This consideration is essential to achieve the desired ride height and handling characteristics.
