    Modern Aggressive RTR Styling. These RTR Rear Quarter Panel Splitters were engineered to give your Mustang an aggressive street/track appearance. Designed and developed in conjunction with Vaughn Gittin Jr., these RTR Quarter Splitters are meant to be installed along with RTR's Side Rocker Splitters (part# 402317). Featuring a clean, sleek appearance, these Splitters are the same exact ones available on the 2018-2019 Mustang RTR.

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

    Simple Bolt-on Installation. RTR's Quarter Panel Splitters were designed to be a simple install with only minor drilling required. These RTR Splitters include all the required hardware needed for an easy straight forward install. Installation can be completed in about an hour with just basic hand tools. Even though drilling is required, these Quarter Panel Splitters can be removed without issue or damage.

    Application. These RTR Rear Quarter Panel Splitters are designed to fit 2018-2019 EcoBoost and GT Ford Mustangs. Driver and passenger side Splitters are included.

            Great addition

            The parts fit great and had the same finish as the factory plastics, installation was 10 minutes. Great product.

            A fine addition

            Solid product, looks like it was meant to be a nice part of the car from the factory, but since it was not OE, that's the best compliment.

            Look great

            These things look great. I paired theses with some roush aero foil rear valance. Give the GT a real nice aggressive rear

            Easy install and looks great

            Took less than 15 minutes to install altogether, it really ties in with the rocker panels also so it gives the bottom of the car congruity, if you don’t have these for your mustang.... get some!

            Noice Touch

            You can install on base model after cutting out the raised mount with two holes for pin connectors. Adds a nice touch to the rear quarters.

            Looks amazing!!

            It was an Easy install with no permanent modification. Two small holes will need to be drilled but nowhere visible and it’s all lined up perfect. Install took all of 10 minutes

            RTR quarter splitters

            I bought the RTR quarter splitters because I have the side skirts ones. Now the back of the mustang looks so much better. Thanks
