I installed Eibach Pro Kit Springs last month, and they said they can't align my car because I need an aftermarket camber(alignment) kit. Would anyone know where I could get an aftermarket camber kit for my 04 maxima?

 

If they were talking about the rear wheels, the answer is "yes". The fronts can be aligned and should be after the springs are installed.

I had eibach springs installed and did not like the way the rear wheels sat. I thought they were too low, like I had a dead body in the trunk. I changed the rear springs back to stock and the space between the tires and fender look even all around the car.
