Swift made lowering 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.

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.

Swift utilize spring design with fewer coils which not only allows to decrease un-sprung mass, but to also completely eliminate the chance of coil bind, while increasing the amount of usable stroke. Swift designed 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.

 

SPORT SPRINGS.

 

Swift did not develop their 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.
 

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.

 

SPORT 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.

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.

 

 

Swift approached the creation of these lowering springs with 3 goals.

  1. Maintain or improve a smooth, comfortable ride.
  2. Increase handling by reducing body roll and squat in search of overall suspension balance.
  3. Lower the vehicle within tolerance of each vehicle's usable stroke

 

Stable spring constant and enough stroke

Material
Manufactured with H5S/TW. (Tensile Strength=2,000N/mm^2)

Finishes
High durable powder coating specially made for springs.


Widely light weighting improves active performance
By light weighting of springs, much improved 10% restorative powers than before. It materializes that follow-up performance to the road, quick stability of the body at corner and smooth steerage.


Stable spring constant and enough stroke
(Maximum allowance stroke from 30% to 70% ⇒ spring constant tolerance within ±3%)

Racing Involved

In Swift’s impressive motor sports history dated back to 1998, first was with Nissan Skyline GT-R in the Super Taikyu Endurance championship series in Japan. Then Swift got involved with the championship teams in Le Mans 24hrs, Nurburgring 24hrs, Super GT (JGTC), Super Taikyu series, D-1 World Grand Prix, F3, F3000, Formula Toyota, and many other world class races.
