The AST Suspension Lowering Springs for the 2001-2009 Volkswagen Polo (9N) are high-performance coil springs designed to lower the vehicle's ride height by 50mm. Crafted from premium high tensile chromium-silicone wire, these springs are selected for their strength and metal consistency by AST engineers. The manufacturing process involves cold winding, heat treatment to enhance hardness and reduce internal stresses, followed by shot peening, phosphate treatment, and powder coating to ensure durability and corrosion resistance. These springs feature progressive rates on most vehicles, providing improved handling, stability, and a sportier stance without compromising ride comfort. Their construction emphasizes quality and longevity, making them a reliable upgrade for enthusiasts seeking enhanced performance and aesthetics.

Designed specifically for the 2001-2009 Volkswagen Polo (9N) equipped with 1.4TDi, 1.9SDi, or 1.9TDi engines, these lowering springs serve as a direct replacement for the stock springs. They are intended for street use, offering a lowered center of gravity that improves cornering and overall handling. Installation is straightforward as they are bolt-on components compatible with the original suspension setup. The kit includes two springs, tailored to provide a balanced ride height reduction and performance upgrade. Suitable for daily driving and spirited street driving, these springs help achieve a more aggressive look while maintaining ride quality and vehicle control.
