After reading through ( skimming ) all the posts ..... Has anyone just lowered the rear of the car?
Looking at my all stock Z, it looks as if I lowered it an inch the stance would be perfect.

Thoughts, comments.....

I bought my z used, I was staring at it sunday thinking about lowering it, and I noticed my rear actually looked as if it had been lowered. There is definitely less wheel clearance in the rear than the front, and it appears to have a visible negative camber, on the rear.

This might explain some of the odd handling behavior I have been noticing. It was raining though so I didn't get down to inspect it.

From the factory; Z's have twice the negative camber on rear vs. front.
They also have twice as much positive toe.
19 gallon fuel cell will affect the height difference in rear-pending how much you have on.
Hope this help's.
ps: be sure the surface is perfectly level & flat...as with the independent everything;will make a difference on measurement's.

Hey fellas can I have some opinions on Eibach vs H&R vs Swift springs.

Currently I can get new Eibach springs for $230 USD locally in Australia. I would get Swift springs, but I would have to order them from the US $314 USD plus shipping to here which won't be cheap.

Is it worth if or should I get the Eibachs here and call it a day?

Cheers.

They each have a different amount of drop and spring rates.

shadow85 · 03-27-2017, 01:16 PM

Yep I know the Swifts drop 1
~1.2" on the front and the Eibach ~0.9".

Performance wise, should I fork out the extra $ for the swifts, or since I can get the Eibachs cheaper locally go for that one?

Whichever you do, budget for camber arms and toe bolts.

cooltoy · 03-27-2017, 04:01 PM

Spring rates will affect the type of ride quality you will have. Otherwise they all reputable companies.

My mechanic said I should lower the car to camber the wheels in slightly more, but he did not mention to get camber arms while I am at it. What will I need the camber arms for?

You will have issues getting it aligned. Oem does not allow adjustment. Buy camber arms and toe bolts or spend a lot more in tires.

Ok so I am going to grab the eibachs as I can get it cheap here. And eibach alighnment kit.

About 90% of the owners here use swift spring, and for good reason.

So you may be saving money on the springs, but might end up spending it on the shocks eventually.

But the Eibach has a less drop than the Swifts and also has a closer load rating to OEM.

Read somewhere that it is better to keep load rating closer to OEM. Not sure if that is true.

Isn't that kit just toe bolts? Make sure you get the arms as well if they're not included.
