The AST Lowering Springs for BMW 4 430D (07/2013-10/2020) are precision-engineered components designed to enhance your vehicle’s driving dynamics by lowering the center of gravity while maintaining a high level of comfort. Manufactured using advanced cold-coiling technology on state-of-the-art Wafios coiling machines, these springs ensure consistent quality and durability tailored specifically for your vehicle model.
These springs provide a progressive spring rate that balances performance and ride comfort, making them a reliable upgrade over the OEM springs without compromising everyday usability. The front and rear springs lower your BMW by 40mm each, contributing to improved handling, reduced body roll, and a more aggressive stance. Their design supports enhanced stability during cornering and braking, giving you greater confidence behind the wheel.
Crafted from premium materials, the AST Lowering Springs undergo rigorous testing and quality control to meet stringent automotive standards. Their compatibility with a wide range of BMW models from 1966 to present demonstrates the brand’s commitment to delivering tailored solutions for diverse vehicle requirements. Additionally, these springs come with a lifetime warranty against breaking, underscoring their reliability and the manufacturer’s confidence in their product.
Please note, these lowering springs are not suitable for four-wheel drive (4WD) vehicles. Vehicles equipped with M-sport or Adaptive M-sport suspension systems will experience approximately 10mm less lowering effect compared to standard suspension setups.
