This it the hole adjustable upper arm.

It all depends on how much room you have the adjustable ball joints add a lot of length to you knuckle it can cause the upper arm to hit on bumps. Front and rear camber kits are a little different. If the camber kit is set rite it will not affect the handling of the car in fact you can tune your camber to help you in turns. I like to set my camber any were between -.5 and -1.5. The more you get away from 0 the more tire where you will see.

It could also be your front toe is out.
