honestly you don't ALWAYS need a camber kit. Hondas are weird compared to most vehicles off the assy. line. Some need a kit with only 1" drop, some don't need one even at 3"!!
best thing to do is, drop it, then do the alignment. if you can't get it in spec. then aquire a kit. In the time it takes to arrive, and install, you won't do any noticeable damage to your tires. (unless yer driving across country or something)
