The AST Suspension Lowering Springs for the 1999-2005 Toyota Yaris T Sport 1.5VVVT are high-performance coil springs designed to reduce ride height by 40mm, enhancing handling and aesthetics. Crafted from premium high tensile chromium-silicone wire, these springs are handpicked by AST engineers for their consistent quality and durability. The manufacturing process involves cold winding, heat treatment to increase hardness and minimize internal stresses, followed by shot peening, phosphate treatment, and powder coating to ensure long-lasting corrosion resistance. Featuring progressive rates on most vehicles, these springs provide improved stability, reduced body roll, and a sportier stance without compromising ride comfort.

Designed specifically for the 1999-2005 Toyota Yaris (P1), these springs are a direct replacement upgrade for the factory suspension. They are suitable for street and spirited driving, offering a lowered ride height that enhances cornering performance and visual appeal. Installation is straightforward as they are bolt-on components compatible with the original suspension setup. The kit includes the lowering springs only, with no additional components required. These springs are ideal for enthusiasts seeking improved handling and a more aggressive look while maintaining daily drivability on the street.
