    Review & Installation Video

    Equipment and supplies required: isopropyl alcohol, pliers, drill, quarter-inch drill bit, Phillips screw driver, soft lint-free cloth, electrical tape. With an assistant, hold the left rocker splitter in position and visually know where the foam tape is to adhere to the factory Rocker Panel Molding. Remove the rocker splitter. Clean the noted area and apply the 3M Adhesion Promoter to the factory Rocker Panel Molding. Using a pair of pliers, reach into the Rocker Panel Molding pockets as shown and pull the eight push pins from the left side of the Rocker Panel Molding and discard. The Rocker Panel Molding will remain in place with the upper fasteners retaining it to the body. Prepare the rocker splitter for installation by bending, increasing the tape pull tabs. Do not expose or touch the foam tape. Loosely install the left side rocker splitter and eight new push pins. Ensure that the foam tape pull tabs are accessible. Press the push pins in leaving an eighth-inch to quarter-inch gap. Starting at the front and ensuring that the factory Rocker Panel Molding is nested into the recess feature in the rocker splitter, fully insert the eight push pins. The handle of the screw driver works well to fully press the push pins in. Pull the four-tape pull tabs to remove the tape backing. Press the left side rocker splitter into place. Apply firm pressure at three to four-inch intervals along the entire length of the rocker splitter to ensure a strong bond. Using the installed left side rocker splitter as a template, drill five quarter-inch holes into the factory Rocker Panel Molding. Lay several wraps of electrical tape one inch from the tip of the drill bit to act as a drill stop. Install a new push pin into each of the five drilled holes.

    Ready To Rock! Add the same exact Side Rocker Panel Splitters that were included as original equipment on the Ford Mustang RTR designed and developed by Vaughn Gittin Jr. on your very own modern muscle car for a modern aggressive race inspired styling.

        5 Top Rated Questions

        RTR, CDC, and Roush all have identical looking splitters on your site. Are there any notable differences? Width? Matte/gloss finish? Ease of mounting? How should one choose between them (as they are all the same price)?

        • The RTR, CDC, and Roush side splitters are all the same width with the same finish and manner of installation. The difference comes down to brand and warranty. While the CDC option has a limited lifetime warranty, neither the RTR or Roush option offers a warranty on the item.

        Helpful (1)

        Are these any lower to the ground than the stock panels?

        • The RTR Side Splitters will install below the OEM Rocker panels, lowering ground clearance by around 1/2" to 3/4"

        Helpful (1)

        is there any drilling involved

        • Yes, you will need to drill holes for the push pins to attach through.

            Easy install great product

            East install if you wan Cu the directions for the item. No directions are given in the box . Cut the back of 3M tape lightly to break the back cover and peel to expose it(opposite the red tape side. Directions on how to remove that peel are sketchy

            easy and looks great

            install took no time, just jack the car up and put the tape on and push in the pushpins. small and subtle mod but definitely adds a good look to the car, especially when paired with the rear splitters

            RTR IS THE WAY TO GO!

            I put the RTR side splitter, chin spoiler, and rear diffuser on my 2012 mustang and it sure has turned some heads.It gives the appearance of the car being lowered and will also prevent air from going underneath your car. .

            Great Look

            The RTR Side Splitters were easy to install took at least 15-20 minutes to install. Since Installing the splitter I get a lot of compliments on my car

            Very easy to install

            Just jacked up each front wheel and drill through. You will need to drill as the 3M tape alone will fail in a few days it does visually make the car lower and truly complements the RTR rear splitter

            Aggressive Styling

            This product is absolutely amazing, I can not believe how much it changed the stance of my stang. If you are wanting to both give your stang that sinister/mean look and also that lowered appearance without having to lower it then this is the modification product to buy. This product is constructed with the same material as the Rocker Panel molding from the 10-12 stangs, then you already know that this part will last the lifetime of your ride. I would absolutely recommend this product to anybody with a 10-14 mustang.
