You were able to measure .05" using a yardstick with 1/4" resolution?

.4" variance may be due to how much gas is in the tank between your car and the one they measured.

I would say your measurements are pretty comparable to what Eibach got since there are also variations between cars.

As for camber kits, I prefer my car to be at nominal camber which is probably better for straight line work, but not as good on the twisties. Theoretically more even tire wear too.

 

Not really. I measured 28" and 26 3/4" and just subtracted and converted to 1.25" since Eibach posted in that format.

 

Reviving an old, old thread.......

So my son has been driving the G37 for the last couple of years. He and his friend same something about it being lower than they thought it used to be.

So I measured and it has dropped an additional 3/4" on the left front side and an additional 1/2" on the right front side. Rear is just about where it was 4 years ago.

Anyone else have any similar results with well aged Eibach (or others) springs?

I drove it around and all seems to be fine....just lower. Could there be something else I need to check?

 

I can confirm that Eibach's fronts sort of go lower with time. Hope it doesn't go any lower though.
