      Video Review & Installation

      Hey everybody. Justin with here with my detailed review of the RTR side rocker panel splitters available for your 2015 and up Mustang. The splitters from RTR are going to be for any S550 owner out there who really enjoys what Vaughn and his team at RTR have done to the S550 in regards to overall styling and appearance and maybe wants to go about creating their own RTR at home or maybe just really enjoys what the splitters do by themselves.One thing I do really enjoy about this part from RTR is that, yes, it's going to make a statement visually to the exterior of your car, but it's not going to be over the top or gaudy like slapping on a big body kit might be. It's a simple and subtle part that, in my opinion, is going to add to the appearance of the car, but it's not going to hit you over the head. For those of you guys at home that really enjoy what Ford did with the S550 for the most part but maybe would like to add their own little touch, this is going to be a great option.Another thing I dig about the RTR splitter package here is that, yes, obviously they include the larger portion for the side of the car, but as you can tell, they've also thrown in the splitters for the rear bumper. Basically, you're getting four pieces in the kit here. What that's going to accomplish is carry that lower wider look that I think these rockers help achieve all the way down the side of the car and even carry that look into the rear bumper.One thing to point out, guys, if you don't have a premium package equipped car you might have to slightly modify the rear portion here as some of our customers have pointed out in the customer review section.Getting into the construction a little bit, you will notice a high-strength injection molded plastic for the build of the splitter itself. It has been finished off in the same textured black grain plastic as a lot of the factory plastic on the S550, so they look like they could've been a factory-installed part, or at least they're built that way. Another big thing to point out here, guys, no drilling or anything crazy needed when it comes to the install. Instead, you're going to be using the pre-installed 3M tape here on the splitters in addition to reusing some factory hardware, making it an easy one out of three wrenches on the difficulty meter. As for your tools, you're basically looking at a torque spit, a panel removal tool or a flat head screwdriver. Again, you are going to be working underneath the side of the car, so it wouldn't hurt to get the car up in the air slightly just to give you better access. Figure a couple of hours from start to finish to get all four panels installed. Again, guys, to wrap this up here, this is really going to be for those of you at home that enjoy the more subtle styling improvements as opposed to a full body kit or lambo doors for instance. You're making a subtle styling improvement to your S550 without totally going over the top. Be sure to check out the RTR side splitter package in addition to the rest of the RTR lineup for your S550 right here at
