You can't see them in that pic 'cause they're on the front underside:

I basically extended the front undertray out to the sides to fill the pockets between the front bumper and wheel arches, and added a 2010 louvred bellypan to fill the gap between the radiator support and k-member.
Later on I plan to make a custom trapezoidal shaped undertray that extends further back under the oil pan to make the front underside as flat as possible and reduce drag.
Which material did you use for the sheets? I thinks its ABS? Unfortunately I'm not able to get a 2010 heat shield here in Germany and must fabric my own and figure out how to fix it at the front axle (thats more difficult than I thought) And it must be stable up to 145MPH (Autobahn, yes).
Thanks!
My milage is 25 at 70 no rush Autobahn. I don't look at the city milage.
