Swift Springs Manufacturing Philosophy

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.

Swift Springs Manufacturing Philosophy

Maintaining tire grip is the key to faster times and suspension springs take on an enormous portion of this task!
All Springs are not created equal, the diameters and spring rates can be similar, but the process of manufacturing springs plays a huge factor in how they will perform. Through our extensive knowledge in performance springs, we have perfected the process of manufacturing springs that will outperform our competitors.
With this in mind, we set out to produce a new material for coil springs: a proprietary steel alloy we call "HS5.TW". This material was created in order to maintain the 4 factors listed above, as well as achieving the fastest reaction speed possible to get compliance on road surface conditions. Our springs are created with proprietary winding methods, as well as some other trade secrets focused on ensuring our springs separation from the standard market.
In the time since Swift Springs officially opened its doors in 1997, Swift Springs has dealt with many world class race teams in multitudes of different races including road racing, rally, off road, drift, autocross, pavement and dirt oval track, motorcycles, and more. Swift Springs has lifted many racers to a podium finish, and is still continuing to do so. With so much experience behind us, we feel confident that our springs will give you a leg up in any kind of race you participate in.
Try Swift Springs on your vehicle, and experience what many racers are talking about. We strongly believe that you will feel the difference just like every other racer, and you might even wonder why you didn't try it sooner.
Note: Some of our racers are using Swift Springs on 2 corners only, but to achieve the best results from Swift Springs, we highly recommend using them in all corners of the vehicle due to the very different characteristics of Swift springs.
