What is the benefit of a progressive spring rate?

A progressive spring rate means the spring's stiffness changes as it compresses. During normal driving, it offers a comfortable, compliant ride. When subjected to harder forces, like during cornering or braking, the spring rate increases, providing more support and reducing body roll.

Will these springs affect my car's ride comfort?

H&R Sport Springs are designed with a progressive spring rate to balance improved handling with a superb ride quality. While they will feel firmer than stock, they are engineered to remain comfortable for daily driving.

What does 'without self-leveling' mean for fitment?

This means the springs are designed for BMW 5 Series models that do not have the factory self-leveling suspension system. If your car automatically adjusts its ride height, these springs will not be compatible.

Product Details

Made from 54SiCr6 spring steel, these H&R Sport Springs are shot peened for strength and resilience, then block set to ensure they hold their shape. This material choice means they are lightweight yet strong, designed to last. They are engineered to lower your BMW's center of gravity, which directly reduces body roll when you're cornering. This makes the car feel more planted and responsive, improving the overall driving experience.

The progressive spring rate is a key feature here. It means the springs offer a comfortable ride during normal driving, absorbing road imperfections well, but stiffen up when you need them to during spirited driving or hard cornering. This balance is what H&R is known for, and it’s why their Sport Springs are their most popular product. You'll notice a reduced gap between the tire and fender, giving your 5 Series a more aggressive stance. Plus, by lowering the vehicle, you slightly reduce wind resistance, which can contribute to better gas mileage.

These springs are 100% made in Germany and are a straightforward upgrade if you're looking to enhance your vehicle's appearance and handling without going to a full coilover system. Just be sure your BMW does not have the self-leveling suspension system, as these springs are not compatible with that setup.
