They are absolutely perfect, I honestly could not have asked for more out of them. Here is my full review of them:

Quote:

These springs are supposedly the best performance springs available and yet have been reported to ride more comfortably than the stock springs while being called "junior coil overs." I had a hard time believing this initially, but they were worth every penny.

Quality of the Springs: I was honestly a bit disappointed that the springs came powder coated black rather than the beautiful metallic blue color that is advertised on their website but the coat is even and looks very durable. Compared to the stock springs, these look very beefy and much more substantial which I thought was a plus.

Lowering Observations: The kit is supposed to lower the car 1" in the rear and 1.2" in the front to give the car a nice, slightly more aggressive pose. Once the car was settled off the lift and received an alignment, the ride height was already at the marketed drop so I expect it to go a little lower as the springs settle. The drop is very even front and rear and is the perfect look in my opinion: not too low but not too conservative.

Driving Impressions: this was what interested me the most, I had a hard time understanding how this spring can perform so much better (increased spring rate) but be more comfortable than stock. It depends on your definition of comfortable, but it did improve ride quality in a few areas: large freeway bumps, undulations and overpass rises felt much better as the car just felt more planted and settled during and after the undulations. It also had less of a bounding motion. That said, the ride is firmer and was immediately noticeable as soon as I hit the road. It is not a harsh firmness, but it feels much more positive and controlled which is exactly what I was looking for.

I took it through Malibu canyon roads such as Mulholland on my way back from the shop and the car felt PERFECT. There was no noticeable body roll, and steering response as well as turn in felt much more precise and direct. The car was balanced perfectly between the Stillen sway bar set to the firmest setting in the rear and the spring rates, there was no hint of understeer and I felt like I could finally effectively control the car using throttle. Mid corner bumps did not unsettle the car or give a lurching sensation like the stock springs did and it felt suitably firm at higher speeds which kept the car feeling planted.

All in all, I am very very happy with these springs. Here are a whole bunch of pictures in case anyone is interested, both before and after.

Before:

On the lift:

Comparing the stock springs to the Swifts, check out the difference!

And lowered, all around shots: (sorry the car is a bit dirty)

A big thanks to Seb at SpecialtyZ, very quick high quality work at a super reasonable rate.

And a picture of how they look completely settled:

Cars looking good. Yeah I think they did a really good job on these springs. Once again Thumbs up to Swift for this. I've driven several lowered Z's and every time I do I am extremely happy with what I have.

I need to go to the track again soon.

Hey by the way you should re-post your review here
SWIFT Springs in Production
or the other Swift review page. Maybe we can get a sticky going or something.

I will definitely post there after I come back from dinner, I think these springs feel better with speed!

X band is annoying especially because it goes off for most of the false readings, I need to read the instructions and do that then. I was amazed at the difference in build between the stock and Swift springs, really goes to show the OEM compromises.

lol X band is almost completely unused in the USA now. you should definitely turn it off as it's impeding detection of the more critical bands...like Ka. what detector do you have?
