Modern Aggressive RTR Styling

Add aggressive street/track styling to your 2018-2019 Performance Pack equipped Mustang with a RTR Gurney Flap. Designed and developed in conjunction Vaughn Gittin Jr., this RTR Gurney Flap not only adds an aggressive appearance to your Mustang, but also helps to increase downforce (at speed) for improved traction.

High Quality TPO Construction

RTR manufactures their Rear Spoiler Gurney Flap from an injection molded thermal plastic olefin (TPO) material using the original OEM CAD data from Ford to ensure a perfect fit. TPO is an extremely strong material known for its light-weight, superior durability and impact resistance - making it perfect to withstand the hazards of daily driving. This Gurney Flap is completed in a fine grained stippled texture for an OEM factory appearance.

Simple Peel and Stick Installation

No drilling is required for installation. This RTR Gurney Flap is designed to install simply with the pre-applied 3M doubled sided automotive bonding tape. Thoroughly clean the surface of the Performance Pack Pedestal Style Rear Spoiler and then simply peel the 3M tape from the back and set it firmly in place. It is that easy.


This RTR Gurney Flap is specifically designed to fit 2018-2019 GT and EcoBoost Mustangs equipped with the factory Performance Pack Pedestal Style Rear Spoiler.

2018 RTR Gurney flap

Packaged very well. Great directions. 3M tape wasn’t too thick. I really like the factory PP spoiler and this addition enhances what she came with.
