My version of GT500 Front brake ducts (3")
Here is my version of what the brake cooling ducts should be on the 07 & 08 GT500

I used a 2-5/8” ID ( 2-7/8 OD) aluminum tube and cut it to match the existing angle of the front grille. Then made a flange out of 1/8” Aluminum and welded it to the tube .Next I sanded and polished the flange .

After drilling a 3” hole where the existing factory ducts are I inserted the new inlet duct from the front side.

I then fabbed a backing plate to again match the grill angle and hold the tube in place.

Now I installed the brake cooling backing plates that I purchased from (Bruce) ac427Cobra @ SVTP
These are designed to direct the cool air into the center of the rotor to cool both the rotor and the bearings.

Next I installed the new 3” hoses from the from inlet to the new backing plates.

(Note :: the only thing I still have to do is to install an inlet debris screen inside the new tube which I plan to do shortly.)
(This required a lot of time to do and is not something that I could or would do again in the future as a service . I just posted it to share it with everyone .)
PS: These 3" full size ducts flow at least 72% more air than the 2-1/2" Shelby or FRPP kit.
Thanks ,
