Front alignment questions.

I have not yet had my car properly aligned. I have just eyeballed it and been driving it. I have no vibration or wandering. Actually steers pretty good. I have the RMS upper control arms and adjustable lower struts. I have noticed that when i back the car up and stop. the front end looks way outta whack. the driver side especially. top of tire leans way in. when i pull it forward it looks normal. what would cause this? all parts are new and installed with factory torque specs.
