    Hey everybody. Justin with americanmuscle.com 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 americanmuscle.com.

    Could the Rear Rocker Splitters be also installed on any Aftermarket Valance ? I have the Carbon Fiber Rear Diffuser Quad-Tip by Anderson Composites , and was wondering could they also be installed on the new Rear valance ?

    • The RTR Side Rocker Splitters should have no issues working with the Anderson Composites Type-OE Rear Valance. if you are using a different valance other than this, we do not expect it to fit properly.

      Looks Awesome

      They look good. Good quality. Very easy to install. The RTR side splitters give the mustang a more aggressive look especially with the RTR rear diffuser and a chin splitter. It ties them all together. I am definitely pleased with the way my car looks after installing them. Also the look I'm going for.

      RTR Side Splitters

      Overall, a great product and easy install. 1 out of 3 wrenches on the difficulty meter. I do recommend adding additional 3M double sided tape and clean the underside of the factory rockers really good prior to installing.

      Enhances look of lowered car

      These splitters I think are well engineered for the money. Install was simple. Yes push pins get distorted pulling them out, but didn't break and are holding fine. As far as the tape holding, I bought extra adhesive promoter one included pack "NOT" enough. I don't daily my car will see how long it sticks.

      Look fantastic, adhesive, not so much.

      I had the dealership install these along with some other mods, while I love the look after six months the tape peeling off. I RTR had engineered a more secure method of attaching these pieces.

      It's different

      Pretty much all the Mustang's I've seen in my area don't have this; so if you want yours to stand out, this may help. There's not much to say about it other than it looks cool and matches with the stock side rockers pretty well. The main reason why I got these is because I noticed my Cervin's chin spoiler was a bit lower than the side rockers; so these things evened it out a bit. I would not recommend getting them if you have the stock spoiler on front or don't have front chin splitters. Also, I must point out that the pre-mounted 3M tape is the VHB kind. In my experience, VHB doesn't hold up well against the elements. I recommend slapping on some 3M super strength molding tape along with it. You don't have to take the VHB tape off, but it may not hold it down well on its own. Second, be really careful when taking out the push pins that hold down the side rocker splitters. You do not want to damage them unless you like the look of sagging side rocker splitters.

      Looks good but????

      So I got one side on and the pins you have pull out are very hard to get out and when you do get them out they are some what damaged from pulling them out with when putting them back in they don’t hold like they did. The 3m tape does not stick very well either. I will suggest that one putting these on did you go to the Ford dealership and get new pins after you pull the old ones out because the old ones are just too damaged to hold the panels up. Another thing is that the stock splash guards that, on the rocker panels cannot be put back on so you can’t use those anymore.

      Great looks, but poor mounting hardware

      The RTR Side Rocker Splitters are of great quality and match the rocker panels and the rest of the OEM plastic perfectly. I followed all mounting/installation instructions exactly, and even purchased extra 3M Adhesion Promoter pads, and new push tabs to make sure I had everything I needed to complete the install successfully. All went well as instructed, and product looked amazing for about 5 weeks. I noticed that the pre-installed 3M tape was not holding up, and came lose, causing the splitters to sag. Attempts to re-fasten failed. I eventually took all four pieces back off the car. I have to get more 3M tape and will fasten each side with self-tapping screws, which in my opinion is the only way to safely secure the side splitters due to their weight. The two pieces for the rear are much lighter, but I will also secure them with screws, since the tape itself does not work properly. Overall, product looks amazing on the car, however, mounting hardware should be upgraded for a more safe and secure installation.

      Recommendation is you drill extra holes and use additional fasteners. When I get out I have to remember not to hit them with my foot.

      Enhancing the look

      Pretty straightforward easy install. Be careful pulling the factory push clips or make sure that your have a few extras on hand. They do snap off. Definitely adds a subtle improvement to the factory splitters. If you're thinking about adding the formed splash guards (like I did), they won't fit with these on though. Overall, easy modification and love the enhanced look.
