AST Suspension Lowering Springs (30mm/30mm) - 2011-2015 Kia Optima 2.0T (TF)

The AST Suspension Lowering Springs for the 2011-2015 Kia Optima 2.0T (TF) are high-performance coil springs designed to lower the vehicle's ride height by 30mm. Constructed from premium high tensile chromium-silicone wire, these springs are carefully handpicked by AST engineers for their quality and consistency. Each spring undergoes a rigorous manufacturing process, including cold winding, heat treatment to enhance hardness and reduce internal stresses, and individual shot peening. The springs are phosphate treated and powder coated to ensure durability and longevity, surpassing the typical lifespan of the vehicle. Featuring progressive rates on most applications, these springs improve handling, stability, and aesthetics by reducing body roll and lowering the center of gravity.

Designed specifically for the 2011-2015 Kia Optima TF models, these springs are a direct replacement upgrade for the factory suspension components. They are suitable for street and spirited driving, offering improved cornering performance and a more aggressive stance without compromising ride comfort. Installation is bolt-on, requiring no additional modifications, and the kit includes the set of lowering springs. Compatible with models equipped with the stock suspension, these springs are ideal for enthusiasts seeking a balance of performance and daily drivability. Proper fitment ensures optimal handling and a lowered, sportier appearance.
