I won't worry about it with an Eibach pro-kit, if you have coilovers you will need a camber kit. Unless you have a serious drop, 2" or more you shouldn't need to worry about shocks atleast for awhile. One thing that you must remember is that tire wear depends alot on the tire you're using, I have 18inch 35 series tires (nitto nt450) and they are so rigid that if I slam the car they stay planted flat.
