I'm not Roxer but any time you change the ride height of the car you need to do an alignment. So yes, if you put on the Z0K shocks and springs you'll need to do an alignment. With my car I did the aggressive GMPP suggested track alignment (-2.5 camber in the front, -1.5 camber in the rear...stock is 0 to -.5 degrees front and rear) when I had it re-done. No excessive tire wear seen yet nor have others experianced any so long as they keep their toe settings close to 0 degrees. In hippos picture you can see his front tires are heavily cambered in too. While his is easy to see, mine you have to look much closer to notice it. The handling improvement from all the mods I did made the car perform light years better than stock. (BC coil overs, Z0k sway bars, DDM front middle and rear braces, lower 1", GMPP alignment, and the new wheels)
