The AST Suspension Lowering Springs for the 2012-2015 Honda Civic Si Coupe (FG4) are high-performance suspension components designed to reduce ride height by 40mm, enhancing handling and aesthetics. Crafted from premium high tensile chromium-silicone wire, these springs are engineered for durability and consistent performance. Each spring is cold wound, heat treated to increase hardness and minimize internal stresses, then individually shot peened, phosphate treated, and powder coated to ensure long-lasting corrosion resistance. The progressive rate design on most vehicles provides a balanced ride, improving stability and cornering response while maintaining ride comfort.

These lowering springs are specifically designed for 2012-2015 Honda Civic Si models with the FG4 chassis. They serve as direct replacements for stock springs, offering an upgrade for street and performance driving. Installation is straightforward as they are bolt-on components compatible with the factory suspension setup. The kit includes the springs necessary for a complete lowering upgrade, making them suitable for enthusiasts seeking improved handling, aggressive stance, and enhanced vehicle dynamics without compromising daily drivability.
