        2014 RTR 3 Piece Rear Splitter

        I bought the RTR 3 Piece Rear Splitter for the aggressive look. I had this vision of how I wanted my Mustang to look and the splitter completed that look. The splitter was installed professionally yet, I found out that the splitter (as advertised) did not exactly fit the 2013-2014 California Special/Boss rear valance that I also had installed professionally. This was a slight hiccup during the install which is why I gave the fit 3 stars. Minus the custom fitment, the splitter looks amazing as it provides a lower looking stance, some downforce from the rear of the Mustang, and compliments everywhere I take the car. It's definitely a must have for any 2013-2014 Mustang!

        I really like the splitter kit but it did not match my side splitter. My sides are textured but the rear had a smooth finish. Overall very nice kit and quality.

        RTR Splitter

        I had the rear splitter painted gloss black as part of the look I'm going for. The fit is great and only takes an hour at the most to put on. Clamp drill screw and its done. The appearance is not strong by it's self but once the new spoiler and new deck panel are on it will high light the hole package

        Totally changed the look

        This was the easiest way to change to look of my car I've ever done. Love the lowered look. Goes great with the Roush side skirts. If your looking for that finishing touch this is it.

        RTR 3pc rear splitter

        The RTR 3 piece rear splitter really pops. The contrast in colors with my race red body really stands out. Gives it that Cobra look.

        Makes it look wide

        The RTR rear 3-piece splitter really gave the back of my mustang a lower/wider look in the back. The 3 pieces were very easy to install with a drill, and some clamps to make proper holes it took about 30 minutes total. Overall i like this product and would recommend it to others trying to give their mustang a different look.

      Would this fit with the Boss 302/GTCS rear valence/diffuser?? i have yet to have seen this combo on anyones car.

      • Yes, the RTR 3pc Rear Splitter (13-14 All) will work with that diffuser.

      Is this a bit flexible? I want to know these splitters are flexible or rigid type compared to Roush Side Rocker Panel Splitters. Thank you.

      • They are pretty stiff compare to the roush side splitter

      GT500 Rear Valance There isn't an exception listed but would this actually fit a 2014 5.0 with quad exhaust conversion?

      • The RTR 3pc Rear Splitter would require trimming in order to properly fit a quad tip exhaust.

      Does this help with down force on the car? And does it need to be painted ?

      • Most splitters/diffusers are designed to reduce drag and increase downforce. That is the main purpose of them. I would say that it should help increase downforce. You do not have to paint this item as it has an OE appearance which is a textured charcoal appearance but you can certainly refinish it to match your paint if you were so inclined.
