      Video Review & Installation

      Hey, guys, Adam here with, and today we're taking a closer look at, and of course installing the MP Concepts Sport Rocker Panel in the Unpainted Finish, available for the '15 and newer GT EcoBoost and V6 Mustang. You should be checking this out if you're looking to add a very unique side profile look to your Mustang, adding an angular and more aggressive muscle car styling, with the sport rocker panel from MP Concepts. First thing I wanna talk about right out of the gate is, out of the box, this guy is unpainted. So, as you can see, we have it bolted up in the unpainted finish. Now, I know it might look black, but it is just a bare ABS plastic material. Now, the ABS plastic is what you'd expect from a lot of aftermarket body panel parts, spoilers, chin splitters, valances, all types of stuff like that. Same thing here, all OEM quality. If you wanna get it paint-matched, you definitely have the ability to do so to your custom paint color, or an OEM color like our race red Mustang here. It's all up to you, but it bolts up right out of the box as-is.This does have a completely different styling, as you can see, compared to the factory one, which we'll take a closer look at later on side by side. But, of course, the back end here is where the big change happens. All across the side profile, it does come out just a little bit farther, and to top off this completely different design here, it does have an open cut-out that has the potential to go all the way through for airflow. Now, I will say if you wanna take full advantage of that, I'd recommend trimming back the wheel well liner here. You won't even have to trim much, just maybe two inches at the absolute most, to get that to go all the way through for the airflow. But, of course, that is optional, not something we're doing here today, since it will just be going back to stock. Now, as far as mounting, it's just gonna use all of the OEM mounting locations. There's about 11 clips underneath here going into the rocker panel. There's three pushpin clips at the front, and then seven all underneath the panel itself, all of which are super simple. You don't even have to break out a ratchet or anything like that. There's no cutting, no drilling. It is a direct bolt-on install.Now, this guy is going to come in right around 300 bucks. You do get the pair, so you get the passenger and driver side, and again, tack in the extra paint cost if you're going that route to get it paint-matched, or paint it to a color of your choice. Now, when it comes to the install, guys, I'm gonna give it one out of three wrenches on our difficulty meter because no drilling, no modification, no permanent modifications at least. This is something you can definitely bolt up in the driveway at home. But just a couple of disclaimers before we jump into things here. Like I said earlier, you do have the option of trimming back the wheel well liner to expose some of that airflow. Not something we're gonna be doing in this video, but you do have the option to do that. It would be very simple. You can even do it with something as simple as a box cutter, if you have a little bit of an accurate hand.Now, aside from that, MP Concepts also lets us know that you have the option to paint the factory paint color that you can see straight through the cut-out here on your rocker panel. Now, some guys might like the look of that. Some may not. As you can see, we have a race red vehicle with our unpainted finish rocker panel, so the race red is pretty obvious through that cut-out. Before you install this, you do have the option of painting the inside of that rocker panel there black, just to blend in a little bit more with the unpainted finish here, but it's also up to you. It depends on if you're painting the rocker panel itself. Keep that in mind when you're moving forward. But either way, if you were to paint that little portion of it, even if you return to stock, it would still be covered by the factory rocker panel, so it's not something you'd see on the vehicle anyway. With that said, you can tackle this in about 30 minutes, maybe an hour from start to finish to tackle both sides here. Simple hand tools like a panel removal tool will do the trick. You don't even have to break out a ratchet and a socket set. I'm gonna show you every step of the process. What do you say to get started?All right, tools used in this install include a panel removal tool, pair of needle nose pliers are optional, and a plastic panel removal tool if needed. All right, first step here, we have to get our factory rocker panel out of the way, and I'm starting at the front here on our passenger side. So, I have the wheel turned a little bit to make it easier to access these three push pin clips. So, we're gonna get these three out of the way, and then move on to the rear. I'm gonna use a panel removal tool for this as well, which is just gonna help pry up on the front, and then of course, the back portion of it. Just like that. Do the same thing for the other two.All right, moving on to the rear, we're basically doing the same thing. It's a little bit tighter here because obviously, you can't turn the rear wheel, and there is only one of them that we have to worry about. So you're gonna put your panel tool back in there, pry up on that guy, and get it off. Next step, we have the vehicle jacked up just a little bit, which isn't necessarily required, but it does make life a little easier. Underneath, there are seven of those pushpin clips here. Now, they're a little bit different, in the sense that they only are one solid piece instead of two pieces that you have to pull up individually, so it makes life a little easier that way. So, you're gonna go under here, and inside of each of these little indents, there's one clip. So, let's get those off of with our panel tool. It's really just this one Christmas tree type clip. I'm gonna put that down and do all seven.All right, so at this point, we're just basically gonna be firmly pulling the rocker panel away from the vehicle. There are some clips on the inside that are holding it on, but if you pull straight back, they'll detach. So, I'm gonna start at the front, just hook my fingers around this pre-painted section, and it's gonna snap off. You're basically doing that same thing all across. For this back section, I'm gonna use a plastic panel removal tool. You just wanna make sure it's not metal, so you're not scratching your paint here. Put this guy in there, and pry back up. All right, there we go. Now we can set this guy side.All right, so we got our factory rocker panel off of the passenger side of our '18 GT here, and it's on the ground next to our MP Concepts sport option. Now, I wanna take you through some similarities and differences between the two, and I gotta say the first thing I wanna talk about is the materials. Now, this is made from OEM-quality ABS plastic. Now, ABS plastic is something you see in a lot of aftermarket options that are built to withstand the test of time, like your factory components. This guy is completely unpainted, as you can see, right out of the box, so you have the option to get it paint-matched to, in this case, it would be race red, or some of the other paint codes out there, or just a custom color of your choice. Now, we're gonna be installing it right out of the box as-is, unpainted, which you definitely have the option of doing.Now, this obviously has a totally different design than your factory one. As far as the running length of it, it looks pretty similar, but it does come out a little bit farther. It's a little bit wider of a body stance, but it also has a completely different end here toward the rear. Through the rear, you're getting that open cutout V-shaped or triangle shaped design here, and a little bit more of an angular finish. Your factory rocker panel is pretty smooth, just like the side profile of the Mustang. It has a couple of these body lines to match, which is also replicated here a little bit in your new option, but ultimately, it's not super aggressive, and it doesn't really stand out. It just kind of looks like another part of the Mustang body. This, however, will look like it is a little bit more aggressive. It adds a muscular styling or a sport styling to the side profile of it, or if you leave it unpainted right out of the box, it even pops a little bit more off the vehicle.Now, you'll see a lot of other pictures out there, especially on the product page, of customers who have it paint-matched, along with some of the guys who kept it unpainted. I will say, guys, as a quick disclaimer, if you're leaving it unpainted out of the box, this is not painted black. It's just bare ABS material, which means you are susceptible to seeing some of the molding blemishes that you get from the production line. And you can even see some of the scratches and blemishes within the finish there, because it isn't primed and it isn't painted. If you're looking to have a black finish like it is out of the box, I'd actually recommend getting it primed and painted an actual black paint, instead of keeping it the bare material, but it does still look very good on the vehicle with it right out of the box.With all that said, we're not transferring over any of the clips from the back of the panel there. We have new ones included in the kit from MP Concepts. All we have to transfer over are the factory push pin clips that we took out of the front wheel well. The back will no longer be using that one clip. What do you say we get started?All right, kicking off the install here, we have to assemble these white plastic clips onto the backside of our new rocker panel. Now, they're really a one-time use clip. So, the reason they give you so many is if you ever wanna go back to stock, you have the option to. You'll have a couple of these left over. Pulling off the factory panel, they most likely break off, so having the new ones here definitely going a long way. You're basically gonna find these little U-shaped clips here, and you're gonna pop these suckers on. They'll snap right in place. You wanna make sure when you're doing this that the knob is facing up toward you. There's about 11 of them. So, let's do this all along the inside of the panel.You can use a pair of needle nose pliers to sort of pinch it into position there. You just wanna be careful not to break anything. All right, so that kind of pushes right in. All right, so I'm gonna slide this guy on, starting from the back, line up those clips, and push them into place. There we go. All right, now you can just start snapping them in. If you open up your door, you get a better view of the edge that meets the body of the vehicle. So at this point, you can start pushing them in a little bit better. Sort of gave it one push right in the middle and it snapped all the way through.Now we can come back here and hit this last one, just like that. Just make sure everything's lined up, and we can shut our door. Now we're underneath the vehicle. We're gonna put the Christmas tree clips back in, these little black plastic pieces. All right, last step here, we're just gonna take the three push pin clips and go right into the front wheel well. Remember the rear wheel well's no longer gonna use that, so this is the last step here, really. Now, once you have those three in, repeat on the other side.That's gonna wrap up my review and install for the MP Concepts Sport Rocker Panels in the Unpainted Finish, available for the '15 and newer GT, V6, and EcoBoost Mustangs.
