The hardest mod I have done yet.....

no tape behind the front bumper or rear bumper

Great. My other ride is a saab 9-2x aero, so in order to get the wrx rounded, the sides of the front of the car were behind the radiator. In order to change those bulbs, you have to remove the battery & the airbox to reveal access to those headlamps.

Removing the air box is the easiest.
