AST Suspension Lowering Springs (35mm/25mm) - 2016+ Kia Optima Sports Wagon 1.6T-GDi (JF)

The AST Suspension Lowering Springs for the 2016+ Kia Optima Sports Wagon 1.6T-GDi (JF) are high-performance suspension components designed to improve handling and aesthetics. Crafted from premium high tensile chromium-silicone wire, these springs are selected for their strength and consistency. Each spring undergoes a meticulous manufacturing process, including cold winding, heat treatment to enhance hardness and reduce internal stresses, and shot peening for fatigue resistance. The springs are then phosphate treated and powder coated, ensuring durability and corrosion resistance that surpasses the vehicle's lifespan. Featuring progressive rates on most applications, these springs provide a balanced ride quality with improved cornering stability and lowered stance.

Designed specifically for the 2016 and newer Kia Optima models with the JF chassis, these springs are compatible with vehicles equipped with electronic damping control (EDC). They serve as a direct replacement for stock springs, offering a lowered ride height of approximately 35mm at the front and 25mm at the rear, enhancing both appearance and handling performance. Installation is straightforward for those familiar with suspension upgrades, and the kit includes the necessary springs for a complete upgrade. Ideal for street enthusiasts seeking improved handling and a sportier look, these springs are suitable for daily driving and spirited driving alike, delivering consistent performance and longevity.
