Default Swift springs review!!!!!

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.



considering they were more than I imagined the springs to be I would rate these a solid 9.5/10
I docked the .5 out of there for the people that want to slam their cars.

Just updating pics. WORK VS FX wheels

I did not cut the bump stops. The springs are made by Swift figuring out the useable stroke of the shock. Also I would assume that the rates are stiff enough to minimize the large movements the stock springs would have had.

No cutting is needed.

CFZ, did you install camber kits yet? Whats the camber looking like? I'm sure they are needed to be 100% in spec, but I don't mind some neg camber.

If tjlazer has similar results, I think I will jump on these. OP: do you have any other suspension modifications?

none. and no I do not have camber kits. That was one of my mistakes. Because I got it aligned as soon as I installed them and so I did not let the rubbers sit in. LOL.... yeah I prob have to get it aligned again.
But at the same time I'm not looking to do factory alignment specs, because I go to the track rather frequently. So negative camber is something I do not have a problem with.

A spring install is very basic so there are no need for instructions. You just swap the springs on the fronts. Rears are extremely easy as you do not even touch the shock.

Basic idea on a 350Z:
