    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.

    Application. 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.

      Went on pretty easy, still had to clamp down on the corners. Used black silicone to finish the job. Looks Great!

      Fit is perfect!

      I thought it was a bit over-priced for what it is but the fit is perfect! It follows the lines of the factory spoiler perfectly. That precision is what you're paying for. Easy to install; the instructions are in color on high gloss paper. That shows a lot in a company.

      Subtle touch with big impact

      This is a must for anyone that wants to keep their PP spoiler but add an aggressive touch to it

      Easy installation ~10-20 minutes

      Product is great and fits very well! I pealed a little bit of tape off so that I had some leaders to pull on, fit the gurney flap into place, and applied pressure while lightly pulling on the 3M cover leaders I had created. After the cover leaders were fully removed I applied pressure to each section of the gurney flap for around 5-10 minutes to ensure that the the tape created a good seal. The only issue I had was that the 3M tape that came on it was not placed very well. Near the middle section of the spoiler(top middle) the tape was too tight and had a created a gap that would not seal and on the backside there was a section that had three little pieces of 3M tape overlapped. It's no big issue as I just removed the tape, cleaned the surface and installed my own tape, but it did cause about another 10 minutes of labor. Big deal, right? ☺
