Yes and almost yes.

The eibach will put you a tad out of spec.
The rear has a little bit less gap than the front.

 

Would you say that the 350Z springs sit nicer then the prokit.

 

No, the 350Z springs are too high for me. I like my fenders to sit right at the tire or even a little tucked in the front. That was how my H&R's sat. rear was flush and the fronts were tucked 1/4-1/2"

 

Of course it matters a ton what size tires you are gonna run. I'm a little lower in the rear but overall sits nicely IMO. I have 45 series tires so the gap isn't too pronounced.

 

any word on if you'd need a camber kit for sure or not? I'm hoping to pick up a set of unrevised springs sometime this spring.

if you DO, anyone know about how much they run?

 

They'll drop you 1" in the front and 1" in the rear. In the rear, for sure you'll need a camber kit...in the front, I've heard mixed stories.

I went w/ the Z springs in the front and Coupe springs in the rear (1/2" drop), as it even's out the fender gap from front to rear (the G sits 1/2" higher up front @ stock). This seems to be a pretty common setup lately, so that's why I went with it...plus it's inexpensive.

 

I had mine put to coupe specs and my fronts are fine. The rear is barely off, haven't observed any crazy tire wear issues. the rear camber kits can be found for around $100 from what I've seen.

 

If you want something stiffer than stock, Eibachs aren't it, they are progressive so they will feel soft most of the time, and will allow the body to roll significantly before the higher springrate coils kick in during a turn. OEM 350z springs are your best bet
