      Description

      Modern Aggressive RTR Styling. Add an aggressive track inspired appearance to your GT Mustang with the same exact Rear Diffuser that is featured as original equipment on the 2018-2023 Mustang RTR. Designed and developed in conjunction with Vaughn Gittin Jr., this RTR Diffuser was designed to offer a tastefully more pronounced Rear diffuser for those who want a bit more in comparison to the subtle factory rear diffuser.

      High Quality TPO Construction. RTR manufactures their Rear Diffuser 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 Rear Diffuser is completed in a fine grained stippled texture for a factory look that helps to hide the appearance of rock and stone impacts.

      Straight Forward Installation. Installation of the RTR Rear Diffuser is simple and straight forward. The Diffuser installs easily with a combination of hardware and 3M automotive bonding tape. However, it will require permanent modification to the stock rear bumper cover to remove a section of the factory diffuser. Installation can be completed in about two hours.

      Application. This RTR Rear Diffuser is designed to fit 2018-2023 Ford GT Mustang and EcoBoost models equipped with dual quad exhaust tips only. Driver and passenger side Diffusers are included.
