and are there any springs coming out that will drop juuuuust slightly lower than the Eibachs? the tanabe ones say .08-1.0 inches.

I don't know of any yet, I'm sure there will be some in that range though. I'm pretty happy with the ride quality of the Eibachs. I've had other Eibachs on previous vehicles and I think they did a great job with the spring rates on these. They work really good with the stock shocks. Your going to sacrifice a little ride quality, but not much. Here is a pic of my car after installing the SPC camber arms, this is with 20mm spacers in the rear and the camber brought more back to stock position.
The Eibachs will give you a slight neg camber when first installed. Link to thread:
http://www.the370z.com/intake-exhaus...tml#post110864

I think that is the same range as the Eibachs.
If you want just a minimum drop, go with the 2009 Nismo struts and springs. I don't know the exact drop, but most sites are saying 0.4inch or 10mm. They are a bit more expensive ($999 msrp) but if you do a search, you can get them for as low as $699 a set.

man that looks clean!!!! nice pics from the berks.... i will definetely get eibachs.... and yah the drop is noticable... :happydance:

Is camber adjustment absolutely necessary with Eibach springs + 20" wheels?

i appriciate your responce but i want to go the other diresction. lower not higher than the Eibachs.

I am getting my car lowered tomorrow by the best suspension center in our State. I am using Eibachs with 255x35x20" on a 9" rim and 305x30x20" on an 11" wide rim.
Will let you know tomorrow my camber and whether I will need camber arms.

yes theres a huge difference in my opinion, check out the before after pics of my car..
as for camber adjustment.. i would highly recommend it.. the wheels will tilt outward a little bit, and you'll notice it after the install. Plus if you align it, it will push out the rear tires more to make the stance a tad bit wider.

and heres a picture of my car with 20s with eibach drop after read camber alignment

ps: my springs will be for sale soon!!!!

I just had my Eibach springs fitted with my 20" rims.
The drop is very good for a street use at just over 1.2" front and rear. I was actually nicely surprised that the drop was more then Eibach specifies.
My front cross camber is -0.08 and the total toe 0.09
The rear left camber is -2.36 and right -2.43 That's the best we could get.
I'm happy with the front but the rear camber is a bit too aggressive.
I have been advised that the rear camber arms don't work and are a waste of money.
Can anyone of you guys who has already fitted the rear camber arms let me know if they have worked for you and fixed the camber problem.
Thanks.

So how do those spacers work? They attatch to the hub with nuts then the wheel sits up against the nuts??? So just the backs of the nuts are touching the wheel?

Minicobra1, do you have a quick recap of your setup and what you finally settled in with for the spacers?

Ichiba spacers:

1) Version 1 or V2 (any particular reason on which version)
2) Stud replacement or bolt on
3) Size Front
4) Size Rear
5) Could you have gone larger?


Eibach Pro Sport Springs

Rear Camber Kit?

New updated pics?

Thanks
Curtis

im curious, did ur car settle lower than the specs that were given for the eibach spring of.09F &.08R? im just wondering if when the springs settle, that the car will be lower than the specs given ya kno.

^ I do not think the OP is subscribing to his own thread any more. Or he has not been on line in a long time.

anyone know what the spring rates are?

Hey Curtis,

Sorry, haven't been on here in awhile. :tup:

1) Version 1, (stud replacement) safer, lighter, plus bolt on style doesn't fit
the front rims b/c the cut outs are not deep enough in the back to clear
the protruding studs.
2) Stud replacement
3) Front 15mm
4) Rear 20mm
5) 20mm will work fine on front, as far as going larger in the rear, 25mm
would work, but I wouldn't recommend it, unless you plan on never going
wider then the stock 275mm tire. If you want to run wider tires I would
stick with the 20mm out back.
These are the latest pics that Berk took , this is after the SPC camber arms on the rear were installed. LINK: http://www.the370z.com/intake-exhaus...tml#post110864

Not very much, if anything just a couple of millimeters. I don't recall the original ride height, forgot where I wrote that down :icon17: It looks to be pretty close to where it was at when I first installed them. Actually the rear raised up a bit when I installed the SPC camber arms and had some of the negative camber taken out.

Hey Mincobra1, thanks for the great feedback.

I am thinking of going 20mm front and 25mm on the rears for wheel spacers. As I plan on keeping these Rays rims for a wheel. Wider tires on the stock Rays rims…geez now you got me thinking, maybe I should just stay with 20mm on the rears. Dunno…

Thanks for the pics, I saw those awhile back, and I cannot tell from the pics if the rears are flush, and I cannot see much on the front from those pics. Any new ones?

I am ordering a set of SPC rear camber kit, and hopefully I will not need to hog out the toe bolt. I did not have to install the toes bolts on my old 350Z with H&R springs (1.3 drop in front and 1.0 drop in rear) and Koni Yellow. Hoping to get away without having to install it, since I am not gonna be slammed with the Eibach’s. Will be holding off on the SPC Upper Control Arms since I heard the drop is not enough to require control arms. The parts should be at my garage (Z Car Garage of San Jose, CA) along with Berk HFC and the new Injen CAI. I already have the Nismo CBE so I am stuck with it for the time being. Oh...and an oil cooler, which is a must. ZCG will probably make their own oil cooler as they are taking on mine and the bros 370Z' as project cars along with their Red 370Z shop car. Rob Fuller already has labeld our cars as the 370ZBros...lol

So it’s a coincidence that we were thinking along the same line as far as mods go. Btw. I have the Platinum Graphite….no worries though I am NorCal and you SoCal …lol…but my roots are SoCal - San Gabriel Valley, HB, Riverside and OC.

Thanks for all your feedback, great thread!

Hey guys. There are a few members on this thread: http://www.the370z.com/wheels-tires/7937-spacers.html that are having vibration issues with the Ichiba spacers. I know there are many here who are using them with no issues and recommend them. Anyone who would care to comment would be appreciated. I was going to put them on my 370 with the 19" Rays like most have, but am curious as to why these guys are having issues. Thanks.

John

^+1
Real odd, especially since two members chimed in now with Ichiba wheel spacer issues. They both do not indicate what size spacers they are running. If that makes a difference.

I Like it also 1'' is what I'm looking for when the time comes. thanks for the feedback. :tup:

Yeah, hard to say on the 25mm rears, I plan on running 305/30/19's like some others on the forum, It looks like it would be close to flush with that tire. The 275's go in a bit, so the 305's will definitely fill the fenderwell better.
There is a link below to Phimosis thread with pics, he has the 305's with 15mm, so 20mm with that size tire should look just right.
I didn't intall the toe bolt on my SPC, looked like the stock one had plenty of adjustment.
Once you get your HFC's on, you will start liking the Nismo CBE, it really comes alive after that. :-) I'm still switching to Berk when it's available, but the HFC's really make a difference. They are a little raspy when the car is cold starting out, but tends to go away once warmed up. :tup:
Good luck on all the installs :tup:

http://www.the370z.com/wheels-tires/...tml#post103602

I haven't had any issues with vibration, had the car in the triple digits and still no problems. make sure the wheel is seated properly on the centering ring, replacement studs are pressed in and seated flush on the hub flange. I torque my wheels at 85ft lbs (+5lbs over spec) while they are still off the ground. :tup:
Re-check torque after driving 50+ miles.

Thanks Braden, I think I am sold on 20 mm for the rears and when the tires go bald, then switch to 305's. And 20 mm for the fronts with 275's. Sounds like the way to go.

Good to hear about not needing to install toe bolt. I was hoping you would say that.

So what camber settings did you go with?


Can't wait for the Berk HFC paired up with Injen CAI on the Nismo CBE. Eventually I am looking at Fast Intentions exhaust and keep the Berk HFC.

Thanks
Curtis

I can't find my alignment settings, I thought I put them in my iphone, but not there, and I can't seam to find the receipt either :mad: Oh well, I plan on getting it re-done after I get new tires on, probably next month.

F.I. exhaust looks and sounds great :tup: I"m 50/50 on the muffler design though. I've been working with Bryan over at Berk, so I'll be going with their system as soon as it's available. I plan on doing some independent dyno testing, etc., I'll post up some video once it's done, I think they are shooting for mid sept/oct for delivery.

20mm spacers in the rear only with stock 19" Sport Wheels
 

Can someone please confirm that I can install 20MM ICHIBA, version 2
hubcentric wheel spacers on the rear only on my 2009 370z with 19" stock Sport Wheels with no modicifications at all. Will these 20MM ICHIBA, version 2
spacers fit with the stock studs without interferring with the stock wheels? Will the 20mm spacers on the rear only affect my 2009 370z ride quality at all? Please respond to anthony.russo@shearman.com. Your help is much appreciated. Thanks, Tony

I'm using the Ichiba V2 20mm front and rear with no issues, and I used my stock lugs. that's with the stock 19'' Rays

So you're saying the spacers with the built in bolts will work on the front too? Doesn't the stock bolt stick out too far and hit the back of the wheel when it's on?

Since they were installed for me, all they did was to bolt the spacers to the hub and put the wheels back on and used the stock lugs, V2 have no fitment issues like the V1 did. front and rear had no issues, and I have had no problems

Thanks, thats great news.............By the way, did the spacers affect the ride quality at all? Especially, since I want to install the 20MM ICHIBA, version 2
hubcentric wheel spacers on the rear only. Thanks again, Tony

First, the handling was about the same.
Second, the stance of the Z at distance is greatly improved. The Z should've had a stance like that from the beginning....

Thanks.......Much appreciated. I ordered the 20mm hubcentric spacers f0r my 2009 Yellow 370z...........have a great weekend..........

hello guys ... i have rims with offsets of...front at 32 and rear at 30.. dnt knw what size spacer to put on there. the car is lowered on eibach..

so guys what are the stock measurements of caster, toe and camber? front & rear

Search is an easy feature to use.
http://www.the370z.com/brakes-suspen...ent-specs.html

does anyone know if i install Eibach Pro Kit Lowering Springs with Bridgestone Potenza RE-11 tires in 265/35/R19 fronts and 305/30/R19 rears... no spacers, stock Nismo rims... would i rub?

I have these springs but my wheels are 10mm farther out than your stock fronts and I have. 255/40. I rub the plastic where it bulges out at the front where the bumper bolts to the fender. But 265/35 just over 26" and my fronts are a huge 27.1" diameter. So I think you would be fine from the most part. The negative camber will help suck the wheels in too. I only rub on big dips at speeds over maybe 40mph.

thanks i think im going for it then

What are your tire sizes? I assume you want the spacers for looks and not any handling improvements (which will be minimal).

So what "look" do you want? Do you want them flush or kind of flush?

Also what are your camber specs front/rear? I would say regardless of tire size or camber specs you can easily go out 5mm front/rear, but there is definitely room for more...easily.
