About to lower my '13 maxima with Eibach pro kit springs and puttingon 20" rims. Does anyone know if I'll need a camber kit or not?

 

Yes.

 

You will probably need the 350z rear tie rods that are adjustable to get the rear toe/camber in spec.
The fronts don't need anything.

I'm on eibachs and 20x9 all the way around.

 

Is there a general thread showing 7th gen Maximas lowered with different wheels? If so, I must have missed it. I'm interested to see what a 7th gen looks like with Eibachs and 20s. I'm already bored with the stock wheels, and I'm considering a set of 20 inch wheels for it.

 

The mega rims thread stickies on top.
