Swift Springs Z70-178-090: Performance Upgrades for Your Ride

If you're looking to enhance your car's handling and ride quality, look no further than the Swift Springs Z70-178-090. With over 90 years of experience in industrial spring manufacturing, Swift has established itself as a go-to name for automotive performance tuning. This particular spring model is engineered to provide not just a change in ride stiffness, but a real transformation in how your vehicle interacts with the road.

Why Choose Swift Springs?

Many enthusiasts often swap springs only to notice minimal differences in ride quality. However, the Z70-178-090 takes performance to the next level by delivering:

  • Increased traction for better grip during cornering
  • Smoother weight transfer for improved handling
  • Enhanced ride quality that absorbs bumps without compromising performance
  • Lower tire temperatures for extended tire life
  • A more predictable feel, allowing for confident driving

Technical Specifications

  • Spring Rate: 503 lbs/inch
  • Usable Stroke: 3.7 inches
  • Max Stroke: 4.6 inches
  • Max Load: 2298 lbs

Fitment

This spring is designed to be universal, making it adaptable for a variety of applications. However, keep in mind that depending on your specific vehicle setup, you may need more than one spring for optimal performance.

Material Advantage

The Z70-178-090 is crafted from H5S.TW. material, which surpasses traditional silicone chrome steel. This advanced material allows for fewer coils in the spring design, resulting in reduced unsprung weight and increased stroke length. This means better responsiveness and a more agile driving experience.

Customer Feedback

One 2021 Honda Civic owner shared, “After installing the Swift Z70-178-090 springs, my Civic feels like a whole new car. The ride is firm yet comfortable, and I can take corners with confidence. No rubbing issues even with my wider tires!”

Why was Swift Springs Formed?

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 Experience

Since 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 Equal

All 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.
