Description
The AST Lowering Springs are precision-engineered components designed to enhance the driving dynamics of your BMW 3 Series (316i, 318i, 320i, 328i, 316D, 318D, 320D) manufactured between 06/2012 and 07/2019. Manufactured using advanced cold-coiling technology on state-of-the-art Wafios coiling machines, these springs offer a reliable and durable solution for lowering your vehicle’s center of gravity, thereby improving handling and stability without significantly compromising ride comfort.
Engineered specifically for each vehicle model, the AST Lowering Springs provide a progressive spring rate that balances performance enhancement with everyday usability. This careful calibration ensures that while your BMW sits lower, the suspension maintains a comfortable and controlled response, preserving the driving experience you expect from OEM components. The front springs lower the vehicle by 40 mm, while the rear springs provide a 35 mm drop, resulting in a sportier stance and improved aerodynamics.
Crafted from high-quality materials, these springs are subjected to rigorous quality control processes, guaranteeing longevity and resistance to fatigue. The product is backed by a lifetime warranty against breaking, underscoring AST’s commitment to reliability and customer satisfaction. Installation is straightforward as these springs serve as direct replacements for the original equipment, facilitating a seamless upgrade to your vehicle’s suspension system.
It is important to note that these lowering springs are not suitable for four-wheel-drive (4WD) vehicles. Additionally, for cars that already feature standard factory lowering, the effective lowering height will be reduced by the amount of the existing drop.
