Your almost at 90 degrees of rotation before you clear the the lip of the kicker. For a 180 it's unnecessary. Like others have said focus more on popping off that lip and leading with your shoulders/head. The more air you get, the less need you'll feel to rush the rotation.
Also, before you move to a 360, get that 180 hammered down. No need to run before you can walk. If you focus on 3's you'll have more issues going back to 180's and even bigger problems with 5's.
