The AST Suspension Lowering Springs for the 1986-1996 Audi 90 Quattro Coupe are high-performance suspension components designed to reduce ride height by 35mm, enhancing handling and aesthetics. Crafted from premium high tensile chromium-silicone wire, these springs are meticulously handpicked by AST engineers for their quality and consistency. 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 durability and corrosion resistance. Featuring progressive rates on most vehicles, these springs provide improved stability and cornering performance while maintaining ride comfort. They are engineered to withstand the rigors of daily driving and spirited driving alike, offering a reliable upgrade for enthusiasts seeking a lowered stance and enhanced handling.

The springs are intended for street use, providing a lowered ride height that improves vehicle dynamics without sacrificing ride quality. Installation is straightforward as bolt-on replacements, and the kit includes the springs themselves. Suitable for street and performance applications, these AST lowering springs are ideal for drivers looking to improve their vehicle’s stance and handling characteristics while maintaining reliability and comfort.
