AST Lowering Springs For BMW Z4 sDRIVE sDRIVE 20i/sDRIVE 30i 11/2018-, Front 30 , Rear 30

The AST Lowering Springs for BMW Z4 sDRIVE 20i and sDRIVE 30i (from 11/2018 onwards) represent a high-quality solution designed to enhance your vehicle's handling and aesthetic appeal by lowering its center of gravity. Manufactured with precision using the best Wafios coiling machines, these cold-coiled springs ensure consistent performance and durability. Their progressive design allows for a reduction of 30 mm at both the front and rear, delivering a sportier stance without compromising the ride comfort typically expected from OEM springs.

Engineered specifically for the BMW Z4, these lowering springs provide a direct replacement for the original equipment, guaranteeing compatibility and ease of installation. The use of premium materials and advanced manufacturing techniques ensures that the springs maintain their structural integrity under various driving conditions. Additionally, AST offers a lifetime warranty against breaking, reflecting the brand’s commitment to quality and reliability.

By lowering the vehicle’s center of gravity, these springs improve handling dynamics, reduce body roll during cornering, and enhance overall driving stability. Despite the lowered stance, the springs are designed to preserve a comfortable ride quality, making them suitable for daily driving as well as spirited performance. This balance between sportiness and comfort aligns with professional automotive standards and customer expectations for premium aftermarket suspension components.

For vehicles already equipped with standard lowering, the actual lowering effect will be reduced by the amount of the existing lowering.
