that is true to a certain degree in some extreme cases where poeple lower there civics like 3" or more it doesnt matter what you do the inside of your tire will be toast
and like everyone else said you should be fine i lowered my old 97 civic the same and i had almost 3 degrees of negative camber and i was fine i did do the washer trick on the rear and it helped out a little i think it just made the wheel just look better in the wheel well more then anything
but the alignment is the most important thing try and find someone good i just have mine done at work by this one old guy he does a great job
