Custom AL Diffuser

I have all of the major pieces cut. The plate needs a 1” radius bent and it will be ready to tack together. Stay tuned.

I’ve got it about 90 percent welded. I should be able to finish and test fit it soon.

Diffuser finish and installed. With the addition of the diffuser, the car is officially complete. This was the last piece of the puzzle. All that is left is to drive and enjoy the fruits of my labor.

Re: Custom AL Diffuser

That looks killer! How did you attach it to the underside of the car?

The fiberglass cover wraps under the steel bumper that has 5 nutserts along the length. The diffuser sandwiches the cover between them. The front is attached at the corners of the quarter panels and on each side of the battery tray in the center. Overall there are nine 1/4” fasteners holding it place.

Re: Custom AL Diffuser

Thanks for the info. I debated trying to fab something like this for my pro-tour build but wasn’t sure how to actually attach it to the car. Here’s a photoshop I made using my other TA as a model. Looks very similar to what you did
