I've always wanted to see what the underside of a T/A looks like. Thanks !
Can we see some more shots of how the air damn ... dam is set up ? It appears as if there is not a real 'scoop' there, but rather a flat panel that the air smacks into and gets pushed into the radiator. Can we see where the radiator is in reference to the air dam ?
Also, thanks for setting the white balance on your camera so that we could see the details in the dark areas. ( Or did you edit them in PhotoShop ? ).
