I appreciate the help. I think you are referring to the camber specs after installation of eibach springs...not just after adding rear spacers. Can the stock suspension be adjusted to look stock and have proper camber specs with spacers of about 20mm in rear?

Yes that is what I would like to know.:tiphat:

I have 25mm on the front and 20mm on the rear (on the stock 18's) that I bought from another member here - I think the fit is great.

So schrute,

Besides the spacers, you didn't need to do any other suspension changes? Sorry to beat this to death, but I just wanted to be sure. Also, which brand of spacers? Ichiba?

Thanks,

Tony

It seems that when some people on the forum put on rear spacers the top of the wheel looks sunk in and looks in need of a camber adjustment and others look nice and perpendicular to the road or flush with the car. Do the spacers that look nice have camber adjustment and others do not. Do you have to buy new camber arms to get the right adjustment? Thanks

If you stand behind your car, you'll notice that the rear fender panel angles downward toward the car's midline. It makes the tire look like the camber is off...it's an illusion.

Buy H&R's and you will be happy. No other work needed.

I have springs and spacers and was able to get a good alignment without camber arms. Spacers won't affect your camber.

Thanks for great help!!!

Thank you for the direct answer!:tiphat:

The contol arm for the stock 370Z are non adjustable, therefore any lowering springs that drop from oem height will place more negative camber on the wheels. There is a little bit that can be adjusted with a stock suspension, other than that you are faced with adding upper control arms and a rear camber kit to add positve camber back in after installing lowering springs.

The rule of thumb is any drop below 0.75 will require a camber kit to bring it back into mfg specs. The Eibachs drop the front 0.9 and rear 0.8. That is borderline out of mfg specs and its a personal choice, some like the more negative camber and some want to save their tires and go for a camber kit.

Myself I went with a rear camber kit and will hold off on the fronts until I see how the tires wear and go from there.

As far as needing a camber kit with just adding spaciners and NO lowering springs. I honestly do not know if spacers alone will effect the mfg camber. I was advised by a reputable shop that installed my spacers on my last 350Z to get an alignment done after spacer install, which lead me to believe something changes in the suspension setup when adding spacers and it may not change the camber BUT may change one of the other adjustments, toe or caster. I never got an alignment done and sold the car soon after and got the 370Z.

EDIT....From Mike's comment above, it looks like spacers do not effect the camber and he was able to get a good alignment with spacers and Eibach springs....thanks Mike!

Hope this helps.

Correct, no other suspension changes. I believe the spaceers are Ichibas, hopefully M.J. will see this and confirm.

Thanks Mike, prior to your response as I was reading this thread I was trying to figure out how spacers would effect camber - seems to me that the plane the wheel occupies relative to the plane of the ground isn't changed by using spacers, just pushed out farther from the hub but at the same relative angle. If I'm missing something someone please let me know.

thats about it, kind of like using a different offset wheel.

Sorry for bumping an old thread, but I'm still a little confused. How exactly does one determine the right size spacer they'll need? After reading this thread (and a few others), it would appear that, to a certain degree, it's personal preference. However, I've noticed that a few guys have commented that their spacers wouldn't fit with their wheels. I'm looking at dropping my Z on Eibachs, and putting on 20" Axis Angles (20x9 front, 20x10 rear). Do I use 15, 20 or 25mm??? Also, and maybe I missed this, but does the offset of the wheel also help determine the width of the spacer? I need a drink...

Offsets on wheels will absolutely have an effect.. you need to know that before you consider a spacer to bring the wheel flush.

Honestly with a correctly built wheel, you shouldn't be running spacers..
