AST Suspension 2025 BMW G99 M5 Lowering Springs - 26mm /15mm

These AST lowering springs are cold-coiled on Wafios coiling machines, a detail that speaks to the precision used in their construction. They are specifically developed as a direct replacement for your BMW G99 M5's factory springs, aiming to lower your vehicle's center of gravity. This adjustment can lead to improved handling characteristics, making the car feel more planted during spirited driving.

The progressive design of these springs is key to their performance. It means they offer a softer initial rate for everyday driving, helping to preserve a comfortable ride similar to what you'd expect from the original equipment. As you push the car harder, the spring rate increases, providing better support and control during cornering and braking. This balance is crucial for a performance-oriented vehicle like the M5, where you want enhanced dynamics without sacrificing too much daily usability.

AST backs these springs with a lifetime warranty against breaking, which is a strong indicator of their confidence in the materials and manufacturing process. While these springs are designed to fit your G99 M5, it's always a good idea to consult the manufacturer's installation guide for any specific hardware or procedures required for a proper setup.
