SWIFT Springs in Production

azn370z

The front gap looks more than the rear gap, which I think makes it look weird. The h&r springs feel like oem to me, I would prefer a little bit more stiff.

The front definitely looks a bit higher than the rear... seems like H&R might be what I'm looking for...

Thanks, takeshima. Much better picture. I guess I'll be going with H&R's also.

I've had Shift springs on my last three cars, so I know there are great... but I just want something lower, and H&R's have been getting very good feedback from owners.

takeshima

I don't see it. Why does it look like the front is a tad bit lower to me. The shade looks like it shades the front tires more than the rears.
but I think the drop is plenty but I'm sure it's not as low as H&R. I'm sure you can't satisfy everybody.

Well I was told that they are making minor changes to the rideheight for the production model, the springs released right now are only prototypes. I'm sure they would be leveling out the body if it is raked, but I'm not sure if its going to be raised or lowered. All we can do is wait and see.

AZN370Z- The Swift are said to be 10k and 10.5k. That is a good amount stiffer than the Nismo. I'm pretty sure they are the stiffest springs on the market now.

Takeshima- I think the car looks great.

yeah the car looks good..it looks straight to me..

Any firm ETA and pricing confirmation?

Guys, look at this picture - good quality side shot with oem size wheels (the nismo looks like smaller wheels?). In this pic, the stance looks great, front and rear.

Zeester

If Swift can make these the same ride height as the H&Rs yet be stiffer, I would be all over these !!

Boost_lee

Straightened out the pics a little bit...





IMO the Nismo picture looks much better when it appears straight

^^^^^ To answer the question below, the quotes above are taken from a conversation with a Swift sales representitive. They should release the middle of next month. I did not ask about pricing but I will see if they will give me a ballpark or if they have set MSRP.

Swift actually goes out of their way to design their springs around the useable stroke of the shocks, so if the shocks lose too much stroke they will not lower it. They also dyno the shocks for every application to see what rates they can handle and for the 370Z they will be only releasing the Spec R's. In other words they pretty much found the highest rate possible the stock shocks can handle. The Spec R's are designed to be cheaper alternative for track guys (instead of coilovers), but extremely comfortable for daily driving.

They told me that the process for them to make the springs takes a while and is fairly expensive, this is why their application's for lowering springs is very limited. They only do one car at a time.

Very unlike H&R that just makes lowering springs based on the stock rates and stock design of springs, I do not feel that they do any kind of research around the vehicle at all. Like this thread....LOL

I just received a message from the sales rep that I have been communicating with. With permission, I am posting the body of the message:


"Hi Russ,

We have done a ton of testing on the 370Z and have made several prototype sets to finally get them made the way we felt was perfect. There are many springs out on the market already that drops the Z a good amount, this is the reason why we are only releasing the Spec R's. The Spec R's are performance springs in which we try our best to squeeze out as much performance we can with just the springs. There are many factors that we look at when we make the Spec R springs, the valving of the shock, the useable stroke of the shock, the suspension design, and the chassis balance.

With the help of several 370Z tuners in Japan which is where most of the racing circuit testing was done, as well as figuring out a stance in which the drop would be perfect and even. We have brought over several prototypes here to test the comfort levels of driving here in the states, From what we have heard and felt ourselves it is indeed more compliant than stock.

These springs can be used on both the Nismo and normal 370Z both with a good amount of performance increases. These springs were designed around the valving of the regular Z. We have found that the valving for this vehicle is fairly aggressive and so we were able to substantially increase the rates.
Thus making it a performance upgrade for the Nismo as well.

As for the price they are priced higher than other brands, we are targeting the people with performance in mind, as we do not feel that these are simple lowering springs.
We have set the MSRP for these at $419 for the 370Z Spec R springs. From what we noticed the selling price is cheaper and can be checked out with your local dealer when they are released.

We appreciate your interest in the Swift product And if you have any other questions feel free to ask.

Best Regards,"

these seem to be a good compromise between eibachs and H&R's..i have the H&R's and they are well lower than the advertised 1.3fr/1.0rr..

Philipp

If a forum sponsor does a group buy on these, I am in!
