Since you are familiar with the Ings kit, do you know if the Ings rear bumper is the same fit underneath as the USDM one? The reason I ask is because I already ordered the front and rear bumpers for the Ings+1 body kit for my '05 STi with the side skirts coming from Japan. I also ordered the Z Power wing with the carbon fiber garney, the carbon fiber canards and the graphics kit. I want to get the APR carbon fiber rear diffuser but it was made to fit the USDM one. Are you aware of any difference underneath where I need the proper fit? Any help would be appreciated.
