Review & Install Video

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 ?

BrookeHouston

  • 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.

    Great upgrade!

    Very easy to install and is subtle yet still sets the car off really well. Match it wth a front splitter and it gives the car a great look without being over the top. I get a lot of compliments from people who can't put their finger on what is different about my Mustang from others they see, but they really like it.

    Fair Quality

    I had a couple issues with installation. 5 out of 16 of my push pins could not be reinstalled. Some of the holes were completely unaligned. The 3M tape should hold up. Also the color and texture is not a complete match. The splitters are slightly darker and smoother. That being said, they look great and I'm certainly keeping them. I just wish I didn't have to worry about the missing pins.

    RTR Side Rocker Splitters

    Had them installed on my 2016 Mustang GT Premium and absolutely love them. I am not a fan of over modified cars, simplicity goes a long ways. Over doing your car seems to happen a lot, so was afraid of purchasing side splitters that were too much. These were perfect, makes the car appear a tad wider/lower and looks natural on the GT. Gives the GT a much sportier look as well, all in all I am very satisfied. Would recommend to anyone looking for a simple, clean, sporty, and subtle addition to their GT.

    Unique Look

    The RTR side rocker splitters do indeed make your S550 stand out from the rest. It's not a dramatic mod that makes the mustang have a different appearance but it's just enough to give it a killer look. The installation is fairly easy just a little time consuming because in my case I didnt use a jack or lift. The only complaint I have is that the rear splitters keep detaching themselves because the 3M provided isn't enough to keep them stuck on to car. I recommend buying a roll of the 3M along with this purchase.

    RTR Rocker Splitters: Simple Install Nets Significant Results

    What a great product. As with all of the RTR parts I've received, these were packaged extremely well. My RTR goodies always arrive unscathed and this is due to the level of packaging used from these fine folks! I made quick work of these and managed to install them in just under and hour. About 40 minutes for the first side, and 20 minutes for the other side, having already done it. These are a direct bolt on, that require no modifications to the factory rocker panels. This subtle, yet aggressive addition will have your S550 standing out in the crowd! Another home run from the minds behind the RTR Mustang! So proud to have these components on my car!

    Great addition!!

    The RTR splitters are a great upgrade to the factory side splitters. The molding texture is spot on! It adds a slight wider and lower appearance and makes it look even better if you already have a lowering kit installed. I'm not a fan of exaggerated body kits so this is exactly what I was looking for. The installation was pretty straight forward. The only complaint is the amount of alcohol pads and plastic 3M addehision inhibitor that comes with it. No way possible to do both sides with one pad, especially with how quick it dries out. I bought a can of spray addehision for 8 bucks. Just piece of mind to make sure everything is nice and snug. Overall it's a great product and I definetely recommend. Also great customer service from AM as always!!!

    Nice touch

    Installed the RTR side panel splitters over the weekend and could not be happier. Install was straight forward and fitment was perfect on the side skirts. One thing to note, if you do not have a premium rear bumper you will need to modify the rear pieces slightly to get them to work. They are not a perfect fit but complete the look nicely. Overall a solid product from RTR and American Muscle. Fast and free shipping as always.

    Look great!

    I gave this four stars because of the install. These are not as simple as advertised. Removing the factory rivets takes force and frankly destroys them leaving you to find new hardware in their place. Also, the rear panels can flap a little and I used extra double-sided tape to hold them better. Once on though, the car looks great with them on. I need the RTR rear diffuser now to finish the look.

    Weak

    When I opened the package, there was only one 3M Adhesion Promoter pad and two IPA prep pads. I could use my own IPA from home but the adhesion promoter is lacking. I installed everything anyway. Now my driver and passenger side rockers are sagging. The 3M VHB looks like it was peeling off from the rockers itself. Bad quality.

    The product itself was very nice. Fast shipping zero issues during install the only complaint I have is about 1 week after install the rear bumper splitters double sided tape came off of the splitter not the bumper but the splitter itself luckily I have rolls of 3m at home and fixed it in about 10 minutes! Other than that 5 stars looks great!
