What is the best aftermarket spring out in the market?
 

sorry if the same thread is already up somewhere in this forum, but I couldnt find it anywhere so I'm posting it up :p

I'm basically looking for a spring that has nice drop(not slammed) with great handling. I know that most of you will recommend to me to get a set of coilover but since I'm NOT going out for a track so the coilover is not in my option.

Somepeople say that I have to get more than a spring to drop the car such as camber&toe kits etc, while somepeople say camber kits are required defend on the how much it's going to drop. I also have a friend who did not have any camber kits but have done lowering spring then coilovers done to his car.

My questions is what is the best product for the car to have better handling compared to stock springs and how it looks(stiff is always better for me). And are camber and toe kits are REQUIRED to run lowering spring? Is there any springs that does not need both camber and toe kits?

Thanx for you time guys. It's kinda late but HAPPY NEW YEAR!!:tiphat:

Based on what you have mentioned in your Post I would recommend a set of Tein S-Tech springs. These springs offer a reasonable drop while not being slammed.

I don't recommend these simply because we sell them but because Tein is a quality manufacturer that considers not only aesthetics but also the ride.

If you are doing any kind of lowering to the car I would recommend getting the adjusting kits because even if it only drops a little you are still getting something out of line that could easily be adjusted back. You can do the drop simply for looks but you will sacrifice other aspects such as tire wear and handling if you do not get everything lined back up afterwards. Also if you ever decided to go with more drop you already have the adjustment there.

i use to use a lot of tein products in the past, but honestly, they are budget minded and it's a hit or miss with them. i would steer away from tanabe springs as well.

from reading the threads i *think* Swift springs have good overall results. i dont recommend doing just springs though.

Swift Spec R sounds right up your alley.

It really is the best spring out there. No camber kits needed too.

Great timing for the question - thank you.
I'm in the same boat - I want to drop it a little bit, but not a lot.
I am planning to deal with Performance Tuning in Manassas.
They appear to have a good reputation, but they ONLY offer the Tanabe performance springs, which I think is a little limiting.
So I'm definitely in for comments.

I have to put in another vote for Swift Spec R springs; amazing performance for springs with a great ride, and the lowering is spot on as it is not too low but is just right for my taste.

Damn I looked all over the forum for this.

and i posted it in the wrong thread! LOL!

which of them are progressive and which are linear?

if progressive, how much compression needed before the advertised rate?

:iagree:
They are what I went with. :tup:

Me too!

so, who sells the Swifts? I haven't found them on the vendor sights I've checked so far
What are their drops? 1.25" front and 1" rear?
Isn't that really aggressive and won't that cause other problems?
And they really don't need camber kits? - cool!!

I've decided against the Tanabe's.
The drops that they offer (.8" front and 1" rear) are not what I'm looking for.

And I've been looking at the Eibach's, which I really like, but the hidden costs (camber kits) are killing it.

Thanks

Yep, they will let your camber come back into factory specification and in real life will drop the car 1.3" in the front and 1.1" in the rear which is just about perfect.

+1 on Swifts. You can get them here: Swift Spec-R Springs 370Z 08+ and here is the review thread: http://www.the370z.com/brakes-suspen...eviewed-6.html Hope that helps

Just a shameless plug to post pictures of my car, here is how the drop looks:

loving it

hows the sports package Z will look like? you know, you are running with 18 inch wheel so Im assuming they will show a bit difference :p

and how does it ride compare to the stock spring?

And THANKS to all those people sharing your great knowledge!!:tiphat:

Christian - that does look good.

Okay, you all are doing a good job selling me on the swifts.
So this may be my last set of questions (you wish)
1) Did you have to have anything else done when the springs were installed? camber kits, 2 and/or 4 wheel alignments, anything like that (and approx cost)? I'm just looking for other gotcha's before I commit.
2) Any problems with the height? speed bumps and (most normal) driveways especially?

And I agree with brakedrift, THANK YOU ALL for the information; it is greatly appreciated.

There is less wheel gap with the sport rays. There's a pic a few pages back.

You must be thinking of a different thread. But i would like to see the 19" sport rays with the Swifts.

And Christian, what did the Z parked next to you use for a drop?

Here is mine with Nismo wheels. My drop was a little less than andvertised, maybe cuz of my wheel/tire combo, dunno. I also did not need any camber kits or anything else.

You can also see lots more pics of the drop here:

I was actually somewhat hesitant when I read reviews about how these springs had better performance while offering a more comfortable ride. I thought there is no way a spring car have higher spring rates while somehow remaining more comfortable than stock but that is exactly what the Swifts delivered.

Basically, it is what I would call OEM+. It rides just as well even though it is slightly firmer, however it is more comfortable because the spring rates feel much more in tune with what I would expect a sports car to perform at. The car feels much lighter on its feet through turns and there is no wallowing if the car hits any bumps or undulations in the road which lends to a much more secure, planted ride. Paired with my Stillen sway bars, it doesn't get much better in terms of balance and is overall many steps above the exact same car with the same sway bar settings. The Swifts made all the difference.

1) I had an alignment done and I had a more aggressive alignment to improve turn in and steering feel. You will NEED an alignment done, but no camber arms are necessary as all my numbers came back within factory spec. My alignment cost $90 and it was custom since I wanted slightly more aggressive adjustments.

2) Firstly, the only part of the car that "scrapes" are the two small plastic flaps in front of both front wheels. These are replaceable and no other part of the bumper has come close to kissing the pavement. Secondly, I scrape on many things I did not previously haha. Speed bumps are not a big issue as going slowly and approaching them at a slight angle will negate any clearance issues. The worst situations will be going in and out of driveways such as turning off streets into shopping centers and such, by far and away the worst areas! But again, the only part of the car that scrapes are the flexible and disposable front flaps which in all honesty scraped on 75% of those speed bumps and driveways even at stock ride height.

That is Triple's Z and he is riding on Eibach springs with 20mm spacers I believe. His car is definitely slightly lower than mine but it is hard to tell until I get some comparative 19" wheels.

My Review of the Swift Spec R Springs
 

My review right after the installation, all the those points still stand today.

The original pic with the sport rays is in the review thread: Swift springs reviewed

Christian: What shocks did you pair with your new Swift springs? Thanks.

I am running stock shocks, these springs feel like a better match with the valving of the factory shocks. Until Koni releases their sport shocks for these cars, I will be very happy running on OEM dampers.

I've probably been doing research for the last few weeks, trying to dig up all posts from 2009 on...

Still hard to really pin point what I can get. I mean, Swift sounds like the hands down favorite as it offers the best performance along with a great drop...but for where I live, I'm wondering if that drop might be a little to low...along with my F.I. CBE thats coming soon :)

I guess a lot comes down to opinion, but the other two spring choices that say their drop is less than 1" is Eibach or Tein but both are apparently really soft....so it might actually hurt performance.

I guess you can't get it all unless you go Swift? I'm just wondering which is the lesser of 2 evils with eitehr Tein or Eibach......Tanabe is rulled out at this point
