      Review & Installation Video

      Justin: If you're after an aggressive but not over-the-top way to spice up the front end of that 2018 Mustang, then the RTR chin spoiler might just be for you. The RTR option will combine durable injection molded plastic with a textured black finish in addition to a bolt-on design for the mid to high $300 price point. Because the chin spoiler bolts into place using some pretty basic hand tools, let's call it a strong one out of three wrenches on the difficulty meter, with a little bit more on that later in the video. Now, in my opinion, RTR has made some really killer, really unique parts for the Mustang dating back to their S197 parts, the '15 to '17 cars and now the 2018. And two big areas in particular that I really dig with the RTR stuff is their wheel designs and their front chin spoilers. Again, both very unique in the category and certainly stand out amongst some other parts that you're gonna find here on the site. Now for 2018, RTR took that refreshed front end of the Mustang and toned down their '15 through '17 chin spoiler to what you guys see here on the table with me today. And personally, I really enjoy what they did with this option, because with their '15 through '17 chin spoiler, look, it was very awesome, very aggressive, however, it might have been a little much for some casual Mustang owners out there. So, the '18 version again in my opinion is gonna be a nice balance of adding some aggressive looks to the front end but without being too wild or over-the-top. As for the build, well, you're gonna find a very durable material here with the injection molded TPO plastic construction. And listen, guys, if you know Vaughn like I know him, then you know he can be a little rough on equipment. So knowing that, the crew at RTR designed this thing to take some abuse. Finally, the chin spoiler has been given that textured finish much like the other factory plastic found around the 2018. So it's going to blend in perfectly. As for the installation, well, no cutting, no drilling, no permanent modification, instead you're reusing a lot of your factory hardware in addition to some of the stuff RTR has provided you with. So with that said, call it one out of three wrenches on the difficulty meter here. And to give you a better idea of what's expected for this job, here is a detailed walkthrough and a tool breakdown. Man: First thing we're gonna do is raise our car up on the lift. If you guys don't have a lift, that's fine, you can use a jack and jack stands. Once you've got your car in the air whether it be on a lift or on floor jacks, you wanna start off by removing the 19 7 millimeter screws and 2 plastic rivets on the belly pan. [00:02:42] [music] [00:03:19] Once you've got all 19 screws out, you can then remove the 2 plastic rivets. I'm gonna use a pry tool here. Next thing we're gonna do is move into the inside of the wheel well. There are three plastic rivets that we need to remove in here. Once these are out on both sides, we can remove the whole belly pan in one piece. Then we're gonna do the same thing on the other side now. These are he last pins that we have to remove before the belly pan comes out. [00:04:05] [music] [00:04:21] All right, guys, so what we did was we left one seven millimeter screw in place here so that this thing would not fall down and hit us in the head. So once you've got all your pushpins out and all your screws out, go ahead and remove the last seven millimeter screw and this should come out now in piece. Now that you got your belly pan down, you're gonna reveal 10 more 7 millimeter screws that are holding your factory chin spoiler on. We're gonna go ahead and remove those 10 screws and then on each side there are 3 more pushpins that will need to be removed as well. [00:05:05] [music] [00:05:51] Once you've got all your fasteners out of the front chin splitter, we can now grab it, pull it forward, and remove it off of the car. Next thing we're gonna do is remove the 10 speed clips that are located on the backside of our factory splitter. Once we have all 10 of these off, we can transfer them over to our new RTR splitter. I'm using a pick. If you guys don't have a pick, you can use a small screwdriver. [00:06:15] [music] [00:06:57] All right. We can transfer over our speed clips onto our new RTR splitter now. And we're just gonna slide them right into place here. And if they don't seat properly, you can bend the center piece of metal in just a little bit, and that will hook on the inside of the hole to help it seat a little bit more properly. [00:07:30] [music] [00:07:46] We're now ready to get our new splitter installed on the car. Take notice of your three alignment pins. You got one on each end and one directly in the center. You wanna line those up with the holes on your bumper. That's gonna hold it in place for you until you can get some screws started. All right. We've got our new splitter installed now. Starting from the outside edges working to the center, we're gonna start to put the 10 screws back into place followed by the 3 pushpins on each corner of the splitter. [00:08:22] [music] [00:08:59] We've got all of our seven millimeter screws in. Now we can put the six pushpins back into place on the corners of our bumper here. [00:09:06] [music] [00:09:35] We're now ready to reinstall our belly pan. [00:09:38] [music] [00:10:16] That's gonna wrap up our review and install. Be sure to check this out and more at

        Perfect fit and finish!

        I had originally went with another vendors Chin Spoiler and was not impressed at all with the fit and finish. The RTR Chin Spoiler fits perfectly and looks fantastic!. You will need the PP1 belly pan for this to install correctly.

        Product came in a different competitors box and it had holes all over it. Seems like AM just stuffed it in to get it out and had me on the phone verifying that the product I received was actually what I paid for.

        Subtle Agressive Touch

        I wanted to widen the front of my car with out going overboard and this chin spoiler did just that. Sturdy construction and easy installation, little over an hour for the install. Also paired it with MMD winglets under the turn signals. Love the combination. My stang definitely stands out and have been getting several compliments on the look.

        Great quality Perfect fit. Requires lower grill

        Any one reviewing this as not fitting “perfect” is incorrect. The chin spoiler is not meant to be installed with out the Roush high flow lower grill. Any gap is instantly covered by that part as intended. This is why in the description it says it “REQUIRES” the lower grill. It also says the same on the Roush website. People really need to realize this before install. It’s a very intricate install that really should be sold together but I’m assuming Roush wanted to keep the price down. Unfortunately because of this confusion over fitment occurs. If you are willing to spend them money on the full replacement set the front of the 2018 mustang becomes transformed into an even meaner appearance.

        Most aggressive look! (Works on non-PP!)

        Absolutely fantastic finish and quality. Best one out there hands down. Super aggressive look and pleasing from every angle. Works on non-PP cars as well. You don't need the PP belly pan for it to work, it is perfectly stable without it - as mine was for 7 months.

        1 2018 EcoBoost - Mark Installation Time: Afternoon

        Breaks Easy

        I installed this spoiler on my 2018 Ecoboost, looked great but was driving crossing an intersection two days after unstall and tapped a plastic small empty recycle bin and broke off one of the points on the front edge. This should have just resulted in it bouncing off with maybe a scuff. Now i'm left with a $369 piece of scrap plastic. Will try my skills at TPO plastic welding since i was able to recover the broken piece. Beware don't let that spoiler touch anything. Also had to cut my OEM spoiler to use the end piece to fill in the gap it leaves from not fitting correctly so I don't even have one to put back on the car. Done here!

      Will this chin spoiler work with a non performance pack mustang as an upgrade if paired with the Ford JR3Z-17626-B Performance Pack Lower Air Deflector? My research indicates the differences in the lower deflectors (pans) is the reason it would not ordinarily work.

      • We have not tested this with a non performance pack car equipped with the JR3Z-17626-B Performance Pack Lower Air Deflector, but believe this would work.

      I just wanted to be certain that I'm reading this correctly. Your website states that this item only works on GT Performance Pack cars, but your video clearly shows it being mounted on a non-performance pack Ecoboost car. I understand that the under car pan is slightly different between performance pack and regular cars, but it does seem to work even though there are some gaps at the front corners when the non-pp pan is installed at the end of the video. 1 answer
