actually it can be done professionally, but you need camber plates to do it. bosleys tires in wichita ks adjusted all my camber on my car, did a great job at that and only that. after spending 700$ on what was supposed to be a complete suspension repair from a 3ft pothole, i got a 3ft shaft instead. however they can adjust the camber but its gotta be set on a machine and they use plates to do it. thats all i was told when they did mine. i guess the plates are similar to the use of shims...
