Experience the Superior Performance of Swift Springs

Not all springs are made equal, and Swift Springs has invested years of expertise and research into perfecting the art of spring manufacturing. The result of their dedication is the innovative "HS5.TW" proprietary steel alloy, which sets a new standard in the world of springs. Swift Springs has successfully achieved several crucial objectives with this material, including:

• Consistently maintaining the spring rate throughout the stroke
• Offering the maximum possible stroke length
• Providing outstanding durability to prevent spring height loss
• Creating exceptionally lightweight springs

Founded in 1997, Swift Springs has built an impressive track record, catering to diverse applications ranging from oval track and dirt racing to the needs of enthusiastic street drivers. With a wealth of experience and a history of collaboration with world-class race teams and drivers, Swift Springs ensures they have the perfect spring to meet any demand.

This suspension package of Bilstein Sport shocks and H&R Sport springs will lower the ride height and firm up the suspension to provide less bodyroll and better handling. This E24 and E28 suspension package is firm but not harsh and can be used on daily-driven street cars as well as backroad and weekend corner carvers.

H&R Sport springs lower the ride height by 1.25" and stiffens the spring rate. Both combine to lower the car's center of gravity and reduce the amount of bodyroll in corners. The springs are progressive rate so their initial stiffness is actually very compliant and it becomes stiffer as the spring is compressed. This is great for street cars that see bumps and potholes where suspension compliance is key. Overall, they are about 40% stiffer than the stock original springs. The ride quality is a little stiffer than a stock E28 M5.

We use Bilstein Sport shocks as the dampers and they feature Bilstein's patented and innovative valving system. With this system, small bumps and impacts are absorbed as they should be. But the shocks stiffen for cornering and other suspension motions. It's the best of both worlds as the shock self-adjusts based on suspension motion. These fit with the stock strut and shock mounts, making for an easy and clean install.

Although this suspension is listed for the E28 M5 and E24 M6, the original rear self-leveling system must be disabled or removed.
