Swift Springs?

2string1 · 11-30-2021, 10:57 AM

If I put these on my Z will I need to change any other suspension parts? Will these springs help or hurt the ride?

Yes, You will need rear camber arms and toe bolts at the minimum. I would suggest FUCA's up front for Camber adjustment. The springs will lower the car. SPL is what I would recommend for all your suspension adjustment parts.

If I have to do all that, I'm not going to bother with them. Thanks. I'm not looking to race the thing just lower a tad and hope for a smoother ride.

If you lower the car you'll have to do everything Spooler mentioned. It's not specific to just Swift springs.

Cheaper to cut your springs

I understand it's not spring brand specific. I just don't want to put a lot into the suspension.

I'll play Devil's advocate here and say that you *could* lower it with performance springs and just live with the excessive negative camber. Of course, you'll have additional tire wear to deal with. Is your car a daily driver or a weekend warrior? If you only put 3-5k a year, you might be able to stretch tire life 4-6 years if you find something with a higher treadwear rating. By then, it'll be time to ditch that rubber due to age.

Just make sure you get an alignment after the springs settle. The toe gets all out of whack with the drop, and not having this adjusted will burn tires up much more quickly than the negative camber ever will.

I might invest in SPC rear camber arms and toe bolts, but I will live with the front negative camber.

the camber isn't the problem

it's that the toe might get screwed up

also, the stock shocks are not meant for lowered springs with a higher rate, so the ride quality may be compromised

that is why the recommendation for lowering the car is always good quality coilovers and full adjustable arms so that height can be set to whatever you want and the alignment can be corrected

This is what they say about these springs and the OEM shocks. I think they are designed to work with the OEM shocks.

Swift Spec-R Sport Springs were engineered with 3 characteristics in mind.
Modified ride height compared to Sport Springs to maximize optimal suspension geometry.
Further increasing the spring rate to enhance overall performance. The increase in spring rate is based on the upper limits of the vehicles factory shock valving.
Maintaining optimal comfort level for street use.

It is just a weekend warrior and goes in storage every winter. I only put about 3k a year. Maybe....

Are you quoting me the company’s own marketing materials?

To dial your alignment back to recommended specs, you'll need to invest in additional upgrades. Can you get away with using stock dampers for awhile? Likely. Will you see some abnormal tire wear without nominal alignment numbers? Certainly. There's give and take with these type of alterations, and your pocketbook will eventually see a hit, whether it's buying coilovers and suspension parts now, or later when the stock dampers begin to fail or the tires wear out.

I went with performance springs because they were the right thing for me do based on my budget. I never considered coilovers because I've always used lowering springs with success. If you are lowering the car for the sake of better looks, springs will be fine. Just know that there's a lot to factor in if you want the same results with some adjustability.

ZontheRocks · 12-02-2021, 07:37 AM

You can change the sport setup to a Nismo setup and you will get a small bit of lowering and a slightly “tighter” ride. This is what I did and no regrets.

theART · 12-08-2021, 10:43 AM

Installed Swifts last summer paired them with z1 rear arms, no bolts and no front arms, alignment was within factory spec. I would also get either Nismo or Koni shocks to stiffen the rebound.
