H&R 15-18 BMW M3 Sedan F80 Super Sport Spring (Incl. Adaptive M Susp./Competition Package)

These H&R Super Sport Springs are made for your 2015-2020 BMW M4 or 2015-2018 BMW M3 Sedan. They offer a more aggressive drop than standard sport springs, giving your car a lower center of gravity for improved handling and a performance-oriented look. H&R builds these springs using high-tech 54SiCr6 spring steel, which is shot-peened for added strength and resilience. This material, combined with a progressive spring design, helps maintain a comfortable ride even with the significant lowering.

The progressive design means the spring rate changes as it compresses, providing a balance between a smooth ride during normal driving and firmer support when you're pushing the car harder. This results in a well-built spring that offers both a noticeable improvement in handling and a visually appealing stance. Because they are made in Germany, you can expect solid construction and attention to detail.
