Swift Spec-R Lowering Springs - BMW 335i 2007-2013 (E90/E92)
Lease for as low as $/week
Swift made Sport Springs keeps the quality ride you get from the showroom, and adds improved handling and lower ride height for driving enthusiasts and style minded drivers who demand only the best. Swift did not develop the Sport Springs line by simply dropping the ride height. Unlike other manufacturers whose sole focus was style, Swift approached the creation of these lowering springs with 3 goals.
- Maintain or improve a smooth, comfortable ride quality.
- Increase handling by reducing body roll and squat in search of overall suspension balance.
- Lower the vehicle within tolerance of each vehicle's usable stroke.
Most enthusiasts have had experiences with the typical harsh and uncomfortable ride from lowering springs. Performance is often overlooked by manufactures simply because it is easier to lower a vehicle for aesthetics. The end result is usually a bumpy ride that causes a decrease in traction, or excessive worn shocks caused by lowering the vehicle beyond the usable stroke.
We utilize spring design with fewer coils which not only allows us to decrease un-sprung mass, but to also completely eliminate the chance of coil bind, while increasing the amount of usable stroke. Our proprietary material (H5S.TW) has a much quicker transient response, reacting to any road conditions which, in turn, cause a much smoother ride where other springs will skip on the harsh road surface, our spring will react to the road surface as needed.
With the Swift Sport Springs, we expect both street and circuit users to experience an increase in all aspects of suspension tuning from performance to comfort.
Swift developed for each Sport Springs application based on the individual vehicle’s unique characteristics. Put simply, a luxury car will maintain its luxury ride, and sports car will maintain its sports car feel.
Swift Spec-R Springs are designed at the upper limits of the OEM shock valving. Track Tested and Tuned for optimum performance yet keeps the quality ride you get from the showroom, and adds improved handling and lower ride height for driving enthusiasts and style minded drivers who demand only the best.
Swift Spec-R Sport Springs were engineered with 3 characteristics in mind.
- Modified ride height compared to sport springs to maximize optimal suspension geometry.
- Further increasing the spring rate to enhance overall performance. The increase in spring rate is based on the upper limits of the vehicle's factory shock valving.
- Maintaining optimal comfort level for street use.
