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 a consistent spring rate, largest stroke, and lightest weight 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 370Z (Z34), 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.

Designed to be used with stock or aftermarket shocks / struts.
