3. Use Ratchet and break loose the 10mm or 12mm nylock nut that is fastened to the stud. Please be careful and do not drop the nut into the trunklid when removing it.

4. Use fishing string to break the mounting seal from all sides of the wing, please note that fishing string will not pass all the way through due to the mounting stud. (This is not pictured as this car was equipped with the Anderson Composite 2020-2022 Ford Mustang Shelby GT500 Swing Carbon Fiber Rear Wing and the seal was previously removed)

5. Once the rear wing has been removed you will then go in and clean the leftover adhesive/glue using a cordless drill with an adhesive removal cup wheel. Vary drill speed and do not overheat the painted surface, once finished clean the decklid corners with rubbing alcohol or cleaner.

Installation Procedures:

  1. Drilling Preparation: Grab both left and right side wing stand foam pads and pop out the 3 holes in the foam pad, this will be used as the drilling template.

2. Use masking tape to protect the surrounding paint and be able to mark where to drill.

3. Use a punch to tap where you will be drilling, it will help when drilling and deter it from walking away and scratching the paint.

4. Once the preparation is finished, you can prop the trunklid up or use a friend to hold the trunk up when drilling.

Note: You can use a microfiber towel to catch the metal shavings from drilling.

5. Use a 5/16″ drill bit to drill your holes.

6. Verify that the “Dogbone” bracket aligns with the drilled holes.

7. Now that all holes are drilled and aligned you will install the foam wing stand pad onto the trunklid.

8. You now can then go ahead and use the provided hardware to install the wing stands.

9. Once the wing stands are installed you will move onto the wing. It is easier to install with 2 people but doable alone.

10. Use the provided hardware to bolt the wing to the stands as the final step.

11. Enjoy your brand new Function Factory Performance 2015-2022 Ford Mustang GT500 Carbon Fiber Track Pack Rear Wing!

Notes and Takeaways

If you have a Handling Pack / Base Model GT500, your trunk will still have the center holes left over from the OEM swing. We provide the option to buy a carbon fiber cover that will cover the holes left by the OEM swing. Photos of the carbon piece are below.

A recommendation from us on carbon fiber maintenance, get the wing protected with a Paint Protection Film and a Ceramic Coat. This will not only protect the carbon from UV Rays and prevent yellowing but it will bring a vibrant shine to the surface.
