yea we're out of stock and so is Swift... so you can ask around with dealers but I doubt anyone will have any in stock. We are taking pre-orders though :)

abgyak 04-23-2011 02:04 PM

Lucky me i got mine from Kami just before stocks were out.. :happydance: ... Its just the waiting game here 10k miles away from you guys!! :ugh2:

Here are some photos that were taken yesterday at a local shop BBQ/Meet. Photos start on post#7.

The PG had about 50 miles on Swift springs the Red had 25 miles, still settling, fronts are at 26.75" from ground to top of fender with a 1.25" gap from top of tire to fender. They still need to settle. But here they are with 20mm & 25 mm spacers rolling on stock tires 245/40/19 & 275/35/19.

That's exactly what I'm running, but those fronts look a tad lower than mine. Also need to solve a creaking sound in the rear after my install :( .... think it's from the rear brace I threw on along with the springs. Ah well.

The swift spings themselves are an excellent ride. Not harsh at all and VERY planted in the corners. Huge upgrade from stock. I'm glad I invested the extra cash in these over the cheaper H&R.

Tauruszguy 04-25-2011 11:01 AM

Had my alignment done today after the springs settled. I am running H&R spacers 15mm/20mm as well. Here are the results... feel free to chime in!http://www.the370z.com/members/tauru...-alignment.jpg

bigdog1250 04-25-2011 01:26 PM

Got my alignment done this weekend and it resulted in Front Camber of -1.7 & -1.6 (maxed out), and Rear of -2.6 and -2.5. I was super tired/hungover when I picked up the car so I didn't really pay attention to the printout and just drove home. So I called the shop today after realizing there was too much camber out back and they said there was still room to work with on the rear, so I will hopefully have them get me closer to -2.1 on the back 2 wheels.

Pics to come.

Looking to get these springs, anybody know were they are readily available?
Thanks.

KamiSpeed, ARK, Amplified... shop around and get a good price. Each shipment tends to get bought out very quickly so you may have to place an order and wait a few weeks.

Fern to the Z 04-26-2011 03:52 PM

Just placed an order!! hopefully there in by the end of the week that way I can do the install on the weekend.

Dont forget us in the mix!! We also carry these. Ya there's only 50 sets coming this time so its going to sell like hotcakes. Get your pre-orders in!

Fern to the Z 04-27-2011 09:19 PM

Nevermind!!! just found out they were on backorder!!!!:mad:

After 5 days of driving and 160 miles on the springs I am still at 26.75" Fr and 27.00" Rr (measured from ground to fender). I am thinking this is as far as they are gonna drop. I am still at 1.25 from top of Fr tire to fender. I thought I heard BearXX mention he was at 0.75...dunno.

G/L on solving the creaking sound. Let us know if it was the rear brace.

I agree the ride is so smooth and I am running on bald tires that where finding every irregularity grooves in the pavement and pulling the car to one side. I know it's because of the bald tires, but these Swift springs took care of the irregularities and now" look mom, no hands". In the turns on tight U shaped on ramps the car just plants itself lower and lower the more I gas it thru the turn. I have yet to take it on some fast switch backs, those will have to wait until my new RE-11's are installed this weekend and scrubbed in.

The Eibachs are really good springs and do the job well, but if you have the extra $$ and do not mind the lower drop in the front, then Swift fits the bill and more.

ZForce 04-27-2011 10:56 PM

Not bad, I take it your are NOT running any camber arms with toe bolt in the rear, nor upper control arms in the front?

The front right is way out of spec at -1.9 (when OEM is -1.4). I would have had the left front a bit closer to the right if that is all you could muster out of the camber. Not bad, I am hoping for a more on the max side for the fronts to be at -1.4. It may not be obtainable without upper control arms. If that is the case then you can figure more tire wear running at anything greater than -1.4. My fingers are crossed, that I can muster more out of the fronts. I am not worried at all on the rears since I have rear camber arms and toe bolts.

I made a post over in the DIY section and have read this entire thread. I am getting ready to install mine this weekened. Does anyone know what the torque specs are for the various bolts that will be removed??

In for a printout sheet from the alignment rack. That is the Fr / Rr combo setup I would be looking at, probably more in the -1.9 to -2.0 for the rears with that front setup. - 0.3 difference between Fr and Rr with greater camber up front than in the rear.

After seeing two sets of alignment numbers on two different cars without any camber kits, I am disappointed to come to the conclusion that these springs with sport rims and stock tire sizes that the camber WILL NOT be in OEM spec. I hope someone proves me wrong, time will tell with more alignment postings. Keep in mind some may not care or want to be in SPEC, meh... I want to try and get the most out of my very expensive new RE-11's I am about to have mounted this Sat before my alignment.

Mike, your specs look very good, considering you are not running any camber kits. :tup: :tiphat:

You should be able to download the Field Service Manual that is on this forum. It's very usefull and will have all your torque specs.

tsolin01 04-27-2011 11:54 PM

When people say you're within spec on swift springs with no camber kit, it's more like you're maxing out on the spec. If you want to be at nominal spec, (-.67 front, -1.67 rear) then there's no doubt you will need a front and rear camber kit.

Will running slightly out of range camber have significant effects on your tire wear? I'm not convinced that's true.

Thanks for the link! And I'll be sure to post some before and after photos in here

Well stated ...I agree :tiphat:

As far as running slightly out of camber ranger and having significant effects on your tire wear? Only time will tell as I am going to test it and fingers crossed you are right.

I am probably going to be on the max side of spec with a new set of RE-11's and will be hoping to get a good 25k off these tires that are rated for 10-12k miles.

At this point in time I cannot afford $500 + install fees to bring the fronts into nominal spec range. The old saying goes "pay me now or pay me later" and dammed if I don't shell out the extra $$ for upper control arms as they are much cheaper than buying a new set of tires. So I will be in the damn'd that I did not boat. Hopefully not though!

No problem, the table of contents is buried and once you find it, you may want to re-label the file to something like: QUICK_REFERENCE_INDEX_TOC

It makes it alot easier when you have to refer to it in 6 months.

Yes, please do post pics.

If you are running at max stock specs, tire wear will not be too much different than stock. Now, if you go -3 or more, then you will most certainly experience significant additional tire wear.

Also, some additional negative camber helps handling performance substantially both in feel and turn in. Stock camber is suited for long tire life, not performance.

ZForce 04-28-2011 01:33 AM

^ Good to know. I am pleased with the performance I get by staying within a -0.3 difference between Fr -1.3 & Rr -1.0. This setup has provided performance and reasonable tire life at 26k miles. I may try a new setup this time around, more on the performance side, any suggestions?

ZForce 04-28-2011 02:02 AM

I very rarely ever post pics. So here are some initial pics, springs had only been on for 1 day with 50 miles on them.

My setup as follows: Sport rims rolling on stock size tires Fr 245/40/19 & Rr 275/35/19 with wheel spacers @ 20mm Fr & 25mm Rr on Swift springs.

Unsettled springs at 26.75" Fr & 27.00" Rr (measured from ground to fender).

tsolin01 04-28-2011 11:56 AM

Looks good :tup: My drop seems even in the front but the passenger side rear is almost half an inch higher than the driver side. Not sure what could cause that? Anyone else have this issue? I think someone earlier in the thread had the whole passenger side slightly higher but seems to have settled for them. I've had the springs 2 weeks with over 600 miles driven so should be settled already...

christian370z 04-28-2011 06:04 PM

My passenger side is also slightly higher, but not by half an inch. We are honored to view your rare photogasm Zforce! Looks awesome, I am strongly considering moving up to 25mm spacers in the rear.

From previous posts #385, bringing forward to discuss. I have about 170 miles on the springs now on day 6 and they have NOT settled anymore from when I had 75 miles on them. Still have 1.5 gap on three corners AND I also have the rear passenger side ON BOTH Z's at 1.75 gap. I see a pattern here with both of our 370Z's and others stating the same.

I cannot see mine dropping to what Baer383 has (above) at .75 gap on all four corners.

Can anyone confirm if they followed the same install "load the suspension when you tightened everything up" as Baer383 did? And actually what does he mean by loading up the suspension?

Is what Ron suggested (above) be our solution? I did not do my own install and my installer said he did not mess with the upper control arm bolts.

This still only addresses the the overall jacked up height on our cars BUT NOT the .25 higher gap on the rear passenger side.

Up for discussion.

Thanks, I pic whored a bit last night, not the best background but will do for this thread. I will try to get a few more pics with the OEM tires before they get swapped for some paws with more meat on Sat.

ZForce 04-29-2011 01:26 PM

Well I am not sure on this 1.5 gap still, so I am heading over to the dealership to have them check my installers work on the spring install and try to determind the cause for this high gap.

Correct. I am at -1.4 front and -1.9 rears and was told that was in spec. Is that the same as when stock? NO. Do I care? Nope. If I did care I would spend the ~$500 on camber kits! A little more negative camber is not bad, especially on the Z.

Tires are fine so far, 6K miles on them. :ughdance:

So what's the measurement from your fender to the ground through the center of the wheel? Stock height is supposed to be 27.87 in front, 27.99 in rear.

I'm about 26.75" front and 27" rears like the others.

Yea my fronts are 26.75 but then my driver side rear is 26.8ish and then passenger side rear is 27.2 ish... I mean the difference isn't immediately noticeable but I'm kind of wondering what might be causing it...

26.75 Fr & 27.00 Rr

So that would calculate to be a difference in drop for the Front to be 1.12 drop and for the Rear it would be 0.99 drop

Thanks, I can live with this as it,s only a gnats arse difference from the springs rated drop at 1.2 Front and 1.0 drop for the Rear. :tup:

BG40thZ 04-29-2011 09:45 PM

Started my install tonight. Got the fronts on and the car is back on the ground. Looks great so far, definitely a noticeable drop. Going to do the rears in the morning along with SPC camber arms. Will post up pics when its finished! :happydance:

I just had the springs installed today. So far, I am enjoying the ride a lot more. Now I am just waiting to install the spacers, woohoo!

They are on b/o all over. Still waiting for paypal payment from you. :tup: pm sent.

Red__Zed 05-01-2011 11:25 AM

Finally got to do some driving on the new swifts. My toe is still all over the place from the install, but I love the ride. I was convinced these were massively overhyped, but they live up to most of the hype in my mind.

The ride is much better than stock on most roads (really rough ones are slightly worse, as expected), but the reduction in weight transfer side-to-side in turns in notable, as is the slight rearward shift in weight distribution. It definitely helped dial out a bit of the understeer the car tends to exhibit.

ZForce 05-01-2011 11:38 AM

Thanks for the writeup, it's the first I have heard of an improvement in the understeer department. :tup: An alignment should take care of any toe issues. Post up your spec sheet after you get an alignment. The Swift springs are great improvement over the stock springs.
