When it comes to performance tuning, Swift Springs has earned its reputation through years of dedication and innovation. With over 90 years in industrial spring manufacturing, their Z65-228-070 coilover springs are engineered for those who demand more than just a stiffer ride. These springs are designed to enhance traction, improve weight transfer, and provide a smoother ride, all while keeping tire temperatures in check. If you’re looking to optimize your vehicle's performance, you’re in the right place.
Many car owners find themselves swapping springs without seeing much difference aside from ride stiffness. Swift Springs challenges that norm. The Z65-228-070 is crafted from H5S.TW. steel, a material that outperforms traditional silicone chrome steel. This allows for fewer coils, reducing unsprung weight and increasing stroke, which translates to better handling and comfort on the road or track.
Owners of various models have shared their experiences with the Z65-228-070. For instance, a 2020 WRX owner noted, “These springs transformed my handling. The car feels more planted in corners, and I can push it harder without worrying about losing grip.” Another user with a 2019 Civic Si said, “Installation was straightforward, and the ride quality improved significantly. The springs also lowered my stance just right, giving my car a more aggressive look without sacrificing comfort.”
Whether you're aiming for a comfortable daily driver or a track-ready setup, the Swift Springs Z65-228-070 offers the performance enhancements you need. Don’t settle for just any spring—choose a product that’s backed by decades of engineering excellence.

Swift Springs was founded in 1997 in Tokyo, Japan as a motorsports division of Tokyo Hatsujo Manufacturing Co, Ltd., which has been leading the spring industry since 1924. Swift Springs was established to demonstrate their superior engineering by developing the next generation of sport suspension coilover springs. The scope of the project was to surpass the best of any other brand or design in the market by making the springs ultra-durable and lightweight, while still being affordable.
World-Class Racing ExperienceSince its inception, Swift Springs has been led by former racer and suspension expert Kei Yokota and the chief engineer Yasu Saito. Their first-hand experience and involvement within the race industry have propelled Swift Springs through the ranks of the world’s most prestigious races. Swift quickly became the most recognized and respected name in performance coil springs in motorsports all around the globe.
The brand’s impressive motor racing history started in 1998 with a Nissan Skyline GT-R in the Super Taikyu Endurance championship series in Japan. Swift Springs moved on to support championship teams in the 24 Hours Nurburgring, 24 Hours of Le Mans, D-1 World Grand Prix, F3, Formula Toyota, the Super Taikyu series, and many other world-class races. In 2004, Team Goh’s Audi R8 won first place with Swift Springs at the 24 Hours of Le Mans race.
All Springs are not Created EqualAll coilover spring manufacturers claim to have four factors: lightest in weight, largest amount of stroke, most consistent spring rate, and highest durability against loss of spring height. Only the innovative and revolutionary Swift Springs achieve the fifth factor which is having the fastest reaction speed possible to gain compliance on road surface conditions. While diameters and spring rates may be similar across several brands, the spring manufacturing process is what determines exactly how well they will perform. To achieve all five factors, Swift Springs developed a proprietary steel alloy "HS5.TW", as well as a patented winding method that no other coilover manufacturer can duplicate.
Swift Springs provide drivers with a difference that they can feel and several racing benefits. Swift Springs use a very strong alloy, which means they can use a thinner diameter of wire. In turn, the thinner wire is much lighter and extremely vital given it is unsprung weight. Thinner wire also means that there is more gap between the coils with more “stroke” for the spring. This gives the spring more travel and does not “bottom” as early as thicker wire springs. Lastly, Swift Springs prove to be incredibly consistent and reliable. At the end of one year of racing, Swift Springs are typically within .5-1.0 percent of the rate they were when they just came out of the box.
