Caster and S.A.I. will be the most effected. Any time you change the cars highth you are changing alignment, I have seen some who changed tires and needed one. What happens is the angle of load changes. It is like a bicycle or shoping cart, if you look at one you will see that the angle of the tire is behind the load. (on a bicycle draw a line from the center of the handlebars down through the axle of the front wheel) That is why you were able to go "look ma, no hands!" when you change this angle you get either real hard turning or a car that "wanders" on the road. (not good at 4 in the morning when all the cops are out!) My personal thought is to use lowering shackles or sport springs instead of cutting, then go get an alignment.
