AST Lowering Springs For BMW 6 xDRIVE 640 xDRIVE/650 xDRIVE/640D xDRIVE 03/2012-10/2018, Front 30 , Rear 25

The AST Lowering Springs are precision-engineered components designed specifically for BMW 6 xDRIVE models, including the 640 xDRIVE, 650 xDRIVE, and 640D xDRIVE produced between 03/2012 and 10/2018. Manufactured using advanced Wafios coiling machines, these springs ensure exceptional quality and consistency. Their cold-coiled construction guarantees durability and reliability, meeting the highest industry standards.

These springs provide a substantial lowering effect—30 mm at the front and 25 mm at the rear—effectively reducing the vehicle's center of gravity. This adjustment enhances handling and stability without significantly compromising the ride comfort associated with original equipment manufacturer (OEM) springs. The progressive design of the springs allows for a balanced combination of improved performance and driver comfort, making them an ideal upgrade for discerning automotive professionals and enthusiasts alike.

AST’s commitment to quality is reflected in the comprehensive lifetime warranty against breaking, offering users confidence and long-term reliability. These lowering springs are direct replacements tailored to fit the specified BMW models precisely, ensuring seamless installation and optimal performance.
