Ok, I've been looking closely at the areas of my car that can be quickly modded at minimal cost and effort but I'm stick scratching my head about two parts.
Not my car, just an image of it.
Now down to business. On the doors is a molding piece, would its removal positively have an affect on reducting Cd, and helping airflow, or should it just stay in place. It seems to be nothing more than decoration.
Secondly, would it be better to block the hood grille (where the badge is) or block the bumper grille. I can't block the big hole infront of the drivers tire yet due to the air intake being in that location. It appears that I could block the grille at the badge, and block the outer two squares of the bumper grille.
If I went that route I could angle some coroplast to give me more of a pointed end than the current bumber design, on to the grille block and seal over the passenger hole to allow air to get directed that way. This would extend my front end almost 4 inches. I'll draw up some sketches of what I mean later and repost them here.
