Is the slight rubbing from every day driving? That makes me a bit worried about my choice of 275/35 up front! Christian, I forgot what tire sizes you are running.

Cool! When I get home from work I'll finish with the rear and then take it for a spin. Im all beaten up from trying to get all of that done without an impact gun, specially to install new studs, remove the bolt that holds the shock to the lower control arm and to compress the springs, freaking nismo springs are hard! I went and bought an electric impact wrench and did the other side in 1/3 the time.. TOTALLY worth it! Anyway I will let you guys know how it turns out!

Found my em on the tracking #...woot..woot...mine will be here Weds.

That is really big for up front. I think 265 is even big, I'd probably go 255. But 305 out back seems mightly sexy. Can't wait for my springs to be on next weekend!

The pictures should be showing up. It seems like the tire is contacting that little tab just slightly, although I wouldn't worry about it at all. If you really wanted, you could probably just trim that tab back slightly as it doesn't do anything really.

I have gone through the canyons once or twice so that probably accounts for most of it right there! I wouldn't be worried, it is very minor and contacts the tread well inside of the side wall so it wouldn't matter if you went with a 275 tire I think. You can always trim it off though, it doesn't serve any real purpose from the looks of it. :tup:

Oh I'm rubbing on that tab already and I'm not even lowered yet. I'm running stock tire size up front too 245/40 but with 9.5 width wheel. I suspect it's been during some slightly aggressive driving or maybe some of the heavier dips on the road... but i'm not really sure

I just got my Swifts on friday and will be installing Monday, can't wait. :happydance:

I received my tracking number on the 5th but the status still says it hasn't been picked up or shipped out yet and it's the 10th now. ?????:confused:

My status never got updated till the day they got delivered. Kami sent mine USPS priority. Got them in 3 days.

Thanks, I can now see the photos. probabaly will wait and see if mine rubs on sport wheels, 245/40 Fr and 275/35 Rr and then trim if neccessary. Oh and I have 20mm spacers up front, so with all this talk about oversizing the tires and now throw in wheel spacers. I am gonna hold off on oversizing until I see a member photos with my same setup.

19"Sport wheels
20mm wheel spacers Front
245/40/19 tires

25mm spacers Rear
275/35/19 tires

Current springs - Eibach
Coming soon Swift Springs
1.2" drop Front
1.0 drop Rear

Oversizing tires on paper may look good on paper, just to find out I am screwed in the long run and have to down size the wheel spacers due to the 4x4 look.

Oh and let's not forget the possibility of needing upper control arms, because of oversized tires. Gonna play steady Eddie this round and keep to OEM tire sizes.


Are you running stock sport wheel tire sizes in those photos? Thanks, I appreciate your input and feedback. :tup:

I received my tracking number April 5th and tracking fro delivery Weds 4/13/11. I would call Sakuta or Billy on Monday. They probably just forgot to update thier website. Yours is going to Italy right? That could be the hold up on tracking as it's an international shipment.


You must have it in with KamiSpeed, for priorityshipping! Mine is on the slow truck in San Pablo, CA as of the 8th.

Now get them installed with some pics posted up. :tup:

Sure do, they got here Friday and are already installed :) While I was in there I installed spacers and camber arms. I'm letting the springs settle and will take it for alignment next weekend... Anyone knows of a good alignment shop in Houston?

Getting mine installed @ Kamispeed Saturday morning. :D

you bought through us? if so then its something that always happens with USPS, they seem to not update the tracking until the item arrives haha

Haha, well he wanted them sent out via USPS priority, he had to pay the difference though cuz we always ship out using UPS, sorry for the delay, we shipped out a couple from swift and then had a batch sent here to be sent out from here, all back orders were shipped last week on tuesday and wednesday so there should be no other shipments unsent, if anyone has a missing tracking number let me know and I will get that to you :tup:

^No worries, I like saving $$ and my installer will not be back on the mainland until today, so Weds delivery works out fine. Now if I could just find the right tires to go with 20mm /25mm wheel spacers. I dread these days when I am the first with a setup and having to take a chance.

@Kamispeed, I have heard different feedback on the break in period before getting an alignment. Do you need some miles (100 miles) on the springs before an alignment or not?

Lucky you and I heard you sprung for control arms. Be interested in seeing your before and after alignment printout. Seems no one ever posts these up anymore.

Front does not look that bad. I think I did a good job calculating the length of the arms. Rear is another story though, I can tell just by glancing that there's difference on camber between the 2 wheels. Rear camber is already adjustable on stock arms and having an extra adjusting point on the spc arms just makes it harder to calculate. I could have done a better job by being more careful, measuring and marking but it was 2am and I wanted to get it done haha. I will post my sheets once I get the aligment done.

anyone looking for 370z springs there is one last set left, PM me

^ get em while they last (and not for long).

Saku, did you see my question a couple of posts back? Thanks!

Man I called just in time as the tech barely put the first spring on. I told him about the OEM sleeve that needs to move over to the new spring. Phew! Stinks I won't get to see my car done until sometime tomorrow (been almost a month without the Z).

I'm crossing my fingers the new tires will work out, and hopefully I can get away without a camber kit for a short while. We'll see how alignment goes tomorrow.

Haha you have a lot of posts do you have the particular post number?

Yes I bought them through you. I just received them in the mail yesterday. Not a bad turn around at all! Thanks. Now for the install...hopefully soon.

What OEM sleeve? Please enlighten me, I plan installing the springs/spacers this weekend myself.

He is talking about the thin rubber that goes on the spring side to keep the coils from contacting each other.

And the factory put the front ones on the bottom to keep the spring from rubbing on the strut.

Baer I did about 25miles today on the springs. Rear wheel gap is gone but the front is still there. There's like 1.5 - 2 inches between the tire and the fender. Is it supposed to be like that? From the pics I've seen I'm guessing (hoping) they will settle more

I just measured mine ,and it's pretty low I have .75in all the way around.

You may want to check your control arms.

Did you load the suspension when you tightened everything up?

Just got mine installed today and the drop so far looks like an inch all around. The springs did come with instructions to use the oem sleeve on the new springs and it even had a photocopy of what it should look like. As long as your installer sees that it should be fine.

I can definitely see some noticeable negative camber so I'm planning to get an alignment in a couple weeks. I suspect with the amount of driving I do, the springs will probably settle in by tomorrow lol.

So far it doesn't look like I'll have any rubbing issues with 19x9.5 +30 front with 245/40 tires and 19x10.5 +8 rear with 285/35 tires. Only issue I have now is scraping on my driveway lol

Edit: Oh yea btw, the ride on these is very similar to stock and not harsh at all. Also feels like it absorbs road imperfections better and not as bouncy. I got these mainly for the drop so any performance improvements is icing on the cake.

Here ya go Saku....haha

Sounds like there is some initial driving required to get the springs to settle.

Ron, sounds like you went the string and srting bubble level toi get the initial alignment...props...you have more patience than me.

Digitonium and Baer383, thanks for the reminder about the OEM sleeve. There is a pic posted earlier on this thread or maybe the other thread. Glad Swift is including a cheat sheet in the box. Digi...what tire did you go with and sizes?

tsolin01, thanks for the feedback and tire sizes, this will help me in deciding which size to go with.

bigdog1250, I will get the alignment sheets over to you before the weekend.

My order is due on Weds.

Crap I didn't. So, take the wheels off, loosen the camber arm bolts, raise the susp with a floor jack and then tighten the camber arm bolts. Right? How much should I raise it, until shock and spring are fully compressed?

Any tracking no for me Bro Saku?

This one took months of debating. Since I plan to push more power in a couple of months, the best combo with the Hankooks I could find were 275/35 and 305/30. Some owners already have this combination, so I'm hoping and praying this is going to work.

I'm jealous... there was barely any progress with my car (even took the day off to sort it out). My car was dropped off at a shop last Thurs. after completing the body repair to get the clear bra installation, but they never touched it for several days. So they rushed the job yesterday morning and the car arrived at my dealer after 9:30AM, but the tech was busy working on another car. An hour later he removed wheels and, I transported them to a wheel shop. They finished my wheels around 2:30PM, and the all that's done on my car when I left was 1 spring that needed to be taken out to put the rubber sleeve on. Hopefully I get the car back today... it has been nearly a month without the Z.

Imagine the labor cost of putting on new springs, brake rotors, pads, lines, fluid. Gotta get them overtime hours haha. [sigh]

hey I don't think there is a necessary break-in time, I'd say like anything else just drive it around for a week or so to let things settle and then go for the alignment :tup:

sorry none yet, should be shipping out today, I'll send you an email once its all ready :tiphat:

Here are some pics with mine installed after a day so far. I'm liking the stance right now but might put a 10mm spacer up front in the future. These are the perfect drop for me, anything lower and I won't be able to drive anywhere lol

The drop looks great- the front definitely needs to come out. I think you should add spacers to the front and rear to really flush them out.

WOW tsolin, that's looking very nice :yum: this will look even better as the springs fully settle.

Car came back from service after getting some work done. I was told that toe is good, but they couldn't get the camber and caster adjusted the way they wanted and recommended I come back with a camber kit. Initial impression from driving a few miles is that the ride quality is not degraded, and it feels stock. I haven't scraped anything going up and down the driveway. In fact, I used to scrape the exhaust cans every once in awhile with the stock springs and thinner tires (285/30). I need to double check steering range with the drop and fatter tires. The FI exhaust can is about 3" off the ground.

Below are previews of the current look... higher quality pictures after getting the headlights modded, lip installed, etc.

Dang, your ride is like perfect.


Mine showed up yesterday, won't be back in town to install til the weekend though.

Thanks guys. :tup: I don't really want to mess with spacers so I'll probably just leave it be for awhile.

DIGItonium, ride looks good man. Glad you got your car back in one piece. :tup:
