AST Lowering Springs For BMW 5 525D/530D/535i 07/2003-03/2010, Front 50 , Rear 50

The AST Lowering Springs are precision-engineered components designed to enhance the driving dynamics of your BMW 5 Series 525D, 530D, and 535i models produced between 07/2003 and 03/2010. Manufactured using advanced Wafios coiling machines, these springs are cold-coiled to ensure optimal durability and performance. Their progressive design effectively lowers the vehicle’s center of gravity by 50 mm on both the front and rear axles, contributing to improved handling and stability without significantly compromising ride comfort.

Crafted from high-quality materials, the AST Lowering Springs serve as a direct replacement for the original equipment manufacturer (OEM) springs. They have been specifically developed to meet the exact specifications of your vehicle, ensuring seamless integration and reliable performance. The springs maintain a balance between sportier aesthetics and functional improvements, making them ideal for drivers seeking enhanced road grip and a more dynamic driving experience.

In addition to their performance benefits, these springs come with a lifetime warranty against breaking, reflecting the brand’s commitment to quality and customer satisfaction. This warranty provides assurance of long-term reliability, allowing you to invest confidently in your vehicle’s suspension upgrade.

Please note that these lowering springs are not suitable for vehicles equipped with level adjustment systems or four-wheel drive (4WD). Furthermore, vehicles fitted with factory sports or M-Sports suspension systems will experience approximately 25 mm less lowering than the standard specification.
