      Review & Installation Video

      Hey, guys, Adam here, with Today, I'm bringing you a quick overview and installation of the Roush Rear Spoiler in the Unpainted Finish, available for all 2015 and newer Fastback Mustangs. In this video, of course, I'll be going over the styling and appearance you can expect from the rear spoiler from Roush I have here today. I'll even touch on the materials and construction. I'll top the video off with the install, which I'll let you know upfront, does require you to do some drilling into your factory trunk lid. So you want to keep that in mind going forward, which is why it'll get a two out of three wrenches on our difficulty meter.The Roush Rear Spoiler I have here today, in the unpainted finish, will be for any 2015 or newer Fastback owner, who's looking to pick up a rear spoiler with a Ducktail-style design and a race-inspired quality, but is willing to do some drilling into the factory trunk lid to make it happen. The Roush Rear Spoiler you see here offers what other options on this site also offer, which is basically a Ducktail-style, race-inspired design, only difference being this is coming from a very reputable name brand such as Roush.Now, with that said, if you're rocking the stock OEM flush mount style spoiler sitting on the top of your trunk lid, this one isn't going to be a huge change, but, of course, will offer a noticeable styling. What I mean by that is, instead of sitting flush on top of the trunk lid, this is gonna sit flush on the lip of that trunk lid, giving it that Ducktail-style feel. Now, although it's not a huge change from that subtle flush mount-style spoiler from the factory, if you didn't pick up that performance pack and your S550 didn't come from the factory with a spoiler, this is going to make a huge difference to your rear end. Adding a spoiler to an S550 that otherwise did not have one, it can really change the exterior appearance, and I think for the better.Now, as I mentioned in the beginning, to get this one installed, you will have to do some drilling into your factory trunk lid. Now, if that's not something you're willing to do, unfortunately this option may not be for you. But if you are willing to do so, it's not the toughest job in the world. It just adds that extra step, but I'll get to that install in just a second. One thing I do wanna point out, though, if you're concerned whether or not the factory holes that are drilled into your trunk will be visible, once you make the transition to the Ducktail, I will say yes. However, the kit from Roush does include pushpins to plug those holes to make it not so noticeable, and of course, add a little bit of a subtle design to it. Now, of course, those pushpins are gonna be black, but, of course, you could paint those along with the unpainted option here once you take it to your paint shop. If your S550 did not come with a factory spoiler, you don't have to worry about that, because, of course, you don't have any factory holes drilled in the first place.As far as materials and construction goes here, Roush had this manufactured out of a lightweight, durable, blow-molded ABS plastic, a very durable material, long-lasting lifetime, of course, something very commonly used in the after-market world, especially when it comes to body parts like the spoiler. On top of that, it comes right out of the box in this gray base material, unpainted of course. You could take this to your local custom paint shop to get it paint-matched to your factory colors, or any customized color of your preference.As far as the price goes, if you're interested in this rear spoiler from Roush, and you're okay with doing the drilling, or having a professional do it for you, you could pick up the part itself for just south of 300 bucks. Now, in my personal opinion, not too bad of a price tag, but of course, when it comes to adding the cost of getting it painted at your local paint shop, you could tack that up and the price starts to rise.

        Love It

        I didn't get my spoiler from AM, but I somehow managed to finesse the last pre painted Ignot Silver Roush Spoiler from LMR for $150 during their Black Friday Sale. I'm pretty sure I actually got the last one they had. Anyways, this spoiler looks amazing. The install instructions are great and it's a pretty easy spoiler to install. Do make sure to be careful when drilling the entry holes from the bottom of the trunk. I thought i wouldn't need a stop of any kind, but i was wrong and ended up with a tiny little doink on the top of my trunk. It's literally tiny, but still could have been easily avoided.

        2016 V6 Mustang Roush rear spoiler

        The spoiler was easy to install after my painter matched the red. I did order this one that covered up a small ding on the trunk lip.

        Great spoiler!

        Install was pretty straight forward but you definitely want measure twice and drill once. If you don’t feel comfortable drilling holes in your mustang then get a professional to install it. The spoiler comes with templates which make it much more user friendly but you still need to drill eleven holes in the trunk. The end product is stellar and gives the car a great look. I went with the unpainted version and coated it myself but if you don’t plan on painting it on your own then spend the extra money on the prepainted one, it’s worth it. I would recommend this to any mustang owner looking for a more aggressive look without going over the top. Great product.

        Item was well packaged and everything was there. Had a friend of mine, who is a body man, do the installation. Looks great and he said it was not hard to install. Glad I spent the money!

        Nice look

        I love the look of this. I just wish it came in Wimbleton White for the 50th limited. Had to have it painted, installation was a little iffy but everything turned out great.

        Completely changed the look of my V6 base! I didn't have a factory spoiler so I had my body shop paint it and mount for me.

        Not a good replacement for GT Mustang

        I have purchased Roush products for my 2016 Mustang GT and have been pleased. I wanted to go with Roush for the spoiler but the Roush spoiler mounts on the back of the lid. The existing spoiler on the GT mounts on the top so if you choose this as a replacement you will have holes exposed in your trunk lid. American Muscle did allow the return for store credit and I chose a spoiler that utilizes the existing holes.
