The Case for Lowering Springs


When lowering your vehicle, sometimes the cost effective solution is the best solution.

Aftermarket springs provide advantages that stock coils lack, primarily because manufacturers are more concerned with cost as opposed to performance. Just like coilovers and airbags, lowering springs provide improved aerodynamics by reducing the amount of air that passes below the car. A lowered car has a lower center of gravity which in turn improved tire traction, handling, and stability.

A lowering spring kit from KamiSpeed provides you with the the balance a set of coilovers or air bags can’t provide. Apart from the improved performance aspects, springs will maintain OE-like comfort all at an affordable price. Coilovers maximize performance but comfort and affordability is lost. Air bags maximize comfort and improve some performance but affordability is completely lost. Most importantly however, springs are readily available to fit most types of car models. Lexus, Honda, Infiniti, Subaru and Ford are just some of the name brands we cater to. Buy our high-quality lowering springs and give your car the OEM Plus boost it needs!

Swift - Spec-R Sport Springs Index 2


Spec R springs are wound with the same engineering and material as our sports springs. With the exception of stiffer rates and slight change in ride height; you can expect the same characteristics as our sports springs.



I’m pretty sure other manufacturers would not spend this amount of time nor even have the connections to research and create what Swift can. – Member: shutkoevo

Swift Spec R’s felt very good on AP1 dampers – Member: Adrs2k





In my opinion the drop is perfect for me. I wouldnt even say its a mild drop, it’s much more aggressive than what I was expecting.– my350z: AssAlbert





Swift Springs Review: Found on “The 370 Forum”

Swift Springs Review: Found on “The 370 Forum” 

Member: CFZ 

So just a little background on me I have owned several cars and I am a track junkie. I have always put coilovers on my vehicles though but its come to a point in my life now, where I feel like I shouldn’t make my daily driver so uncomfortable. So I decided to look for the most quality spring I can find. I have always put the Swift coilover spring on my coilovers and then I found that they are making lowering springs for my vehicle. That was when I was already ready to buy.
Anyways I have had several lowering springs, I mean they are just springs so I do not expect much from them. They lower the car generally without any performance gains, and most likely the manufacturer gets the stock springs increases the spring rates a little, and then chops the springs and then mass produces them. I have spoken to Swift several times throughout the long wait and they would explain to me the R&D process they go through in Japan as well as the race teams in japan that are sponsored by Swift to help design the spring.


So as for the review.
So I received these springs friday of last week and then installed them immediately after I came home. Got the car aligned at the local alignment shop and went straight to the Willow Springs the local racetrack the next morning.

For Swift, lowering the car was secondary, their priority was to get the best performance out of the springs maximizing what they can out of the stock shocks. This suspension mod is truly the cheaper alternative to coilovers.

When I first drove on them I immediately noticed that the car felt much smoother than stock. You will notice that the uneven surfaces of the road are completely soaked up. It was exactly the opposite of what I was expecting. I know, seeing that the spring rates are so high, it’s hard to believe. It wasn’t until I first cranked the steering wheel from side to side that I actually noticed that the spring rates were stiffer. There is almost no body roll.
It’s interesting that they are able to make a lowering springs like this.


Now on the track the car felt extremely stable and goes around the corners really well. In fact they did an incredible job making the car neutral. There is almost no body roll, and the car does everything that I ask it to. The steering response was also a very noticeable difference. Through the high speed corners the car was easily adjusted through the control of the throttle. There was no understeer nor oversteer through the high speed course. It was just very controlled.

Over all I have no complaints about the springs at all.

here is what the car looks like. The rubber tophats still need to settle in still and sits a tad bit lower now. This is the perfect amount of drop Im looking for.
