Swift Made Sport & Spec-R Springs.

Let Superior Performance And Comfort Lower Your Car.

Info
View Applications

Sport Springs.

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.
  • 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.

Every Car Have Their Usable Strokes.

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.

Proprietary Material And Design To Satisfy Two Contrasting Factors.

As you can imagine, keeping or improving the comfort level while increasing performance is not an easy task, especially since these two aspects contrast with each other.

Where most of the competition simply gave in to the easier method, Swift Springs decided to tackle this issue by creating our own material (H5S.TW), and unique manufacturing method that works very well for this material. Working in unison, the material and manufacturing method provides a superior level for both comfort and handling. 

The way we design lowering springs.

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.

Bump Rubber.

Suspension usable stroke for the cars now-a-days is very limited compared to before. To let the suspension do its own job efficiently, many car manufactures use bump rubber as a part of a suspension’s functional part, not only to limit the shock stroke but to prevent the shocks from bottoming out. This scenario also applies to real world racing, and we use this as a primary focus when designing the sport springs.

Vehicle Characteristics.

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.

Spec-R Springs.

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.

From HPDE events to SCCA competition, Swift Spec-R Sport Springs are made for the track enthusiast looking to take their vehicle to the next level.

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 vehicles factory shock valving.
  • Maintaining optimal comfort level for street use.

Spec-R Springs are wound with the same engineering and material as our Swift Sport Springs.

With the exception of stiffer rates and slight change in ride height; you can expect the same characteristics as our sport springs.

Note: Vehicle drop rate is based on the year, model and option of the test vehicle, and may vary based on each vehicle condition. All testing is done on manufacture’s original shock absorbers. Replacing the shock absorbers to aftermarket could change the ride height.
