I installed Billy's camber plates year before last. Very simple job. Just keep in mind that with stock sized springs you will be limited in movement, which will restrict how much camber you can get out of them. I got enough adjustment to make a very noticeable difference when I was running RB springs, but once I moved up to coilovers (smaller diameter springs) I had all the adjustment I could ever need. For autocross, I'm running probably about 75% of the camber available to me. But don't feel like you need to wait until you have coilovers to add the camber plates, they're still well worth it when used in conjunction with stock sized springs. Excellent quality part too (of course).
