My main concern is the heat from the exhaust. I won't be able to start this until at least next week or the week after. I am testing the result of my rear seat delete and I just don't have the money to buy material right now. I need to find a way to actually get under my car to take some measurements, it sits low to the ground and I am pretty big. So far I have only checked out HDPE, I will check out the others later. I was thinking I could do something in the shape of a skid plate up front to direct air flow, then that would transition to the bigger belly pan, then maybe a skid plate shape in the rear. I just have to check out underneath my vehicle to see what I can do and cannot do. I'm just glad I have a FWD and don't have to worry about a driveshaft or a rear.

On another note, has anyone looked into underhood air flow? Like the small amount of air that would enter through the grille and the gap between the hood and the grille? I was wondering how turbulent the air would be and its effect on the aerodynamics of the car. I have a mostly uncovered engine bay, no shrouds or anything. A Focus oriented company makes a spark plug cover that would smooth out some of the rough spots. It may not make a difference at all. Just a thought.
