to the naked eye but harder to do if you want to be exact. That is why it's best to lower it first to whatever ride height you want it set at(btw,it won't hurt much performance if your not pushing your Z to the limits, like in a track situation). Then if you care about handling characteristics, then take it to a profesional alignment shop and have them raise/lower it according to weight distribution for front/rear and left/right. That way they will know how much you want it lowered and then tweak it out to balance everything according to whatever you like or need. Plus, you're gonna have to get it aligned everytime you raise and lower the springs anyways because camber will be off. Regards, Jeff
