I understand it is a turbodiesel? If so, the best combination is to keep the engine hot and the intake air cool.

Block the upper grille first. This will keep the engine warm and help the aerodynamics up front. Maybe put openable blocks on both grilles, like I did?

Next, rear wheel skirts.

If the rear spoiler can be easily detached/attached, then I'd do some testing with and without. If it hurts FE, then use the mounting points to attach a Kammback .
