Lowering Springs, 40mm/35mm Drop

AST Lowering Springs are engineered to enhance the handling and aesthetics of 2012-2019 BMW 3 Series F30 sedan, F31 touring, and F34 GT models. These springs provide a noticeable drop of 40mm in the front and 35mm in the rear, lowering the vehicle's center of gravity for improved cornering stability and a more aggressive stance. Despite the significant drop, they are designed as direct OEM replacements, ensuring that familiar ride comfort is largely maintained while sharpening handling and cornering response through progressive spring rates. Crafted from high-tensile steel and coiled on precision Wafios machines, these springs offer exceptional durability and corrosion resistance, ensuring long-term reliability. The vehicle-specific engineering guarantees tailored spring rates and dimensions that perfectly match the BMW 3 Series suspension geometry, promoting factory-like alignment and optimal performance. They are a direct bolt-on replacement for stock springs, requiring no additional modifications during installation. AST provides a lifetime warranty against breakage, underscoring their commitment to quality. For optimal alignment after installation, pairing these springs with camber plates is recommended. It's also advised to inspect existing bushings and shocks before installation to ensure the best possible results. This product is a special order item, with an expected processing time of 3-5 business days before shipping. Professional installation is highly recommended due to the technical nature of spring replacement, which requires specialized tools such as a spring compressor and a 4-post lift for safety. These springs are compatible with both OEM and aftermarket shocks, eliminating the need for additional hardware. The design accommodates all rear-wheel and xDrive variants of the 320i, 328i, 330i, and 335i trims within the specified F30, F31, and F34 generations.
