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.

The rear springs on the 2001-2006 E46 M3 models have a chronic broken spring problem. If it hasn't happened to you yet it will. Springs are nothing more than exposed steel and they rust easily. After a while a section of the spring actually breaks off.

A broken spring is very dangerous - the spring is no longer mounted correctly in the suspension and it cannot support the weight of the car, especially when cornering. The ride also suffers as the suspension is no longer able to absorb the bumps and impacts from the road. Aside from a visual inspection of the spring itself you might notice a clunking sound or banging noise coming from the front or rear. An inspection of the noise should also include other related items in the suspension: bushings, ball joints, links, mounts, etc. We also recommend replacing the rubber spring pads on the top and bottom of the spring because they lose their shape over time.

The factory BMW springs sell for $140+ each. We sold and replaced enough while working in New England that we were able to get a strong grasp of the issue and come up with our own springs that are an improvement over the factory springs in every way. These springs are made in Germany using high grade spring steel that is then shot-peened for longer life and powder-coated for protection. These are the same height as the stock replacement BMW springs which makes them a direct replacement.

Replaces Coupe models only.

Everyone knows the E53 has been notorious for the air ride system to fail. Even BMW technicians will tell you it's not if your air bags will fail, its when. Repairs can become fairly costly as well, with each bag plus labor potential costing you hundreds and hundreds of dollars. Not only that, but the repairs never seem to be permanent, whether its a sensor going off a leaky air bag or the compressor. Get rid of these problems for good, with this Coil Spring conversion kit. Using OEM springs will give you similar ride height as the air ride without compromising handling or comfort.

**Note: Installing this kit will trigger a Self-Leveling Suspension Inactive Light**
