I have a 1997 E39 and my rear tires are having signs of inner tire wear. The car is lowered with eibach pro kit springs and I have OEM M5 wheels, so they are wide and relatively expensive tires soo trying to prevent the nasty wear with a camber kit.

I already bought the rear camber toe kit. I would like to know how much to expect for labor charge?

Would I need to have the car aligned if only the rear camber toe kit is installed?
