New Swift Sport Mach Spec R Springs!
The origin of Swift Springs
Swift Springs was founded in 1997 in Tokyo Japan as a motor sports division of Tokyo Hatsujo Manufacturing Co, Ltd. that has been leading the spring industry since 1924. The purpose was to demonstrate our superior engineering in spring by developing the next generation of motor sports suspension coil springs. They had to have the best characteristics of any brand or design in the market, which required the springs to be the lightest in weight and most durable, and to exhibit the most linear characteristics while still being cost effective. Since the formation of Swift, it has been lead by the former racer and suspension expert, Kei Yokota, and the chief engineer, Yasu Saito.
Their first-hand involvement within the race industry has propelled Swift quickly through the ranks of some of the world’s most reputable races. Swift springs quickly became one of the most recognized and respected name in performance coil springs in many genre of motor sports throughout the world. Being a part of the Tokyo Hatsujo spring corporation. Swift has a large collection of engineering research and development resources. Tokyo Hatsujo springs are used in most light to heavy industries and the dynamic has provided Swift with most advanced spring technologies and innovations available.
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.
In 2004, Team Goh Audi R8 won 1st place at the world renowned Le Mans 24hrs race on swift springs.
H5S.TW
Motorsport's most advanced spring material
Swift made a name for itself on the tracks of Asia, Europe, and U.S. by defying all accepted concepts and speculations about the future, if any, in coil spring science. When many other company were looking at expensive and brittle titanium composites to create the next evolution of springs, Swift was looking at reinventing the entire science of coil spring dynamics. Swift saw that most others are using the old regular silicone chrome material, which was not strong enough. It used a heat tempering method that damaged the strength of the material that requiring more coils, in turn, more weight.
The material was also suffering from a short life span. With springs like this leading the industries, Swift saw room for improvement.
Swift's R & D team created material, called H5S.TW, which is stronger then regular silicone chrome material. Because of this material, we could make the spring wire thinner, and could wind the springs with fewer coils, which greatly decreased weight while dramatically increasing available stroke.
The Swift Advantage
- Regular Spring test
- Swift Springs test on Dirt oval track
- Swift sprigs test on pavement oval track
Super linear rate characteristics: For better traction, smoother weight transfer, smoother ride, and easier set up!
Every spring manufacture uses different method to rate their springs, causing frustration among many racers when they swap brands.
Brand A may test their spring rate at 1st 10% of the stroke while brand B may test at 60% of the stroke. By looking at the diagram below, you will get a clear picture of how this work.
As you can see, Swift springs are within 3% of the spring rate from 20-30% of the stroke all the way to about 80% of the stroke. (the average stroke range for most road race motorsports). Swift tests the spring rate through the entire stroke to provide the best to the best.
Swift's coil engineering vs other brand
Swift's springs are superior to the other brands in every aspect. You see a chart outlining the fundamental differences and a list of the major side effects to the vehicle's dynamics.
Swift Sport Mach Springs Specs:
Spring Rates - 6kg/6.5kg
Drop Rates - 0.787/0.591
Swift Sport Mach Spec R Springs Specs:
Spring Rates - 5.2kg ~ 7.5kg/5.0kg ~ 8.2kg
Drop Rates - 1.2/1.0
