    Video Review & Installation

    If you're a fan of that Shelby GT350 Track Pack styling and want the convenience of a pre-painted part, well, then you should definitely consider checking out SpeedForm's GT350 Style Spoiler shown here in black for your 2015 and newer Mustang. Now, Speedform's option is constructed from durable ABS plastic and is finished in an OE quality Ford gloss black paint for right around 150 bucks. Installation is gonna go down one of two different ways. If you have a factory spoiler installed, you're looking at a straightforward job here that requires no drilling whatsoever. On the other hand, if you do not currently have a spoiler or wing attached, there will be some minor drilling involved. So, because of all this and the variables, the site's just gonna go two out of three wrenches on the difficulty meter here and call it a couple of hours to complete from start to finish as we'll show you later in the video. Now, the spoiler category is a rather large one and will feature mild stuff like the factory blade type spoilers, all the way down to the gnarly carbon fiber GT350R stuff and everything in between.Now, the option that we're talking about here today is another factory-inspired part and one that I think personally will live somewhere in the middle between mild to wild in regards to overall sizing and styling impact, and that is the standard GT350 Track Pack Spoiler. Now, prior to the 2019 model year, Ford did release two versions of the standard GT350, basically, the non-R variant, and that was the Tech Pack and also the Track Pack car. Tech Pack had a very basic and unassuming blade style spoiler, which I thought was almost too subtle for the mighty Shelby. Now, the Track Pack style spoiler, on the other hand, fit the car perfectly, and offered a good amount of aggressiveness, if you will, for a spoiler. Sure, it's not as crazy as the GT350R option, but let's face it, that spoiler is a little much for most casual Mustang owners out there. This guy, on the other hand, perfect right in the middle and just look great on the car.But let's focus in on the Track Pack style spoiler that we have here from SpeedForm. And on the surface, you do have a very durable and lightweight ABS plastic build, with a lot of the same design detail as that OE Shelby option. The flip side is, it's gonna be far less doe than buying an OE Pack directly from Ford, and you're also getting the benefit of it being pre-painted right out of the box in this nice gloss black paint job. Now, this would be ideal for owners out there either looking to match a black car or maybe just prefer the color contrast on any other color Mustang. I do also wanna point out here, gang, that we also offer the same exact spoiler on the site but pre-painted in any different color to match your ride, but the price does jump up dramatically to north of 400 bucks. But let's get into the installation here with the speed forum spoiler and, again, one of two different things to consider. If you have a factory spoiler already installed there's no drilling necessary. You just have to remove that factory spoiler first.On the other hand, if you do not have anything installed on that decklid, to begin with, well then you will need the drill, there's really no getting around that. But to give you a better idea of how this is gonna go down here's a detailed walkthrough of the job along with a quick tool breakdown.Tools used for this install are a clip and panel removal tool, a Phillips head screwdriver, a 10-millimeter socket, a small plastic scraper, a quarter-inch ratchet, an eraser wheel, a power drill, and some 3M general purpose adhesive remover. So, before you can install your new spoiler, you're gonna have to remove your old spoiler. In order to do this we're gonna pop the trunk, remove the hardware and the interior panel.Now I'm gonna use an interior panel tool to remove all the clips that hold this interior panel on and get access to the screws.Next, I'm gonna use a ratchet with a 10-millimeter socket and remove the 4 nuts that secure the wing to the trunk lid. There's one on either side and two in the middle. I don't want to lose that. Gravity is your friend.So, there's also a layer of double-stick tape underneath the spoiler that holds it to the decklid. I'm gonna use a plastic tool and a little bit of perseverance and slowly work my way from one side to the other to pry this off.Now, we've broken all the 3M loose, we can remove our spoiler. Okay, so as you can see there's a little bit of double-stick tape residue left on the trunk lid. I'm gonna use an eraser wheel with a drill, but if you don't have one of these at home, what you can do is use a little bit of adhesive remover and some elbow grease. It'll take a little bit longer but it will get the job done.Now that I've got the heavy residue off, I can go back with a microfiber and some adhesive remover and clean up the rest. Now, you can peel off the backing for the bolt hole gaskets and install them to the bottom of the spoiler.Before I install the spoiler to the decklid, I'm going to peel back the corners of the double stick adhesive to make it easier for me to get everything lined up.So, now we're ready to install the spoiler to the decklid, this part's a little bit tricky. You have to line up before holes with the four holes in the trunk lid, hold it in place, and get the screw started.You have to be very careful when doing this, otherwise you can drop the screws inside the decklid and you can't get them out.Now that I have all four screws very loosely started, I can close the trunk lid, make sure everything's lined up, and start peeling my tape and applying some pressure.Now, I can apply some light pressure and finally go back and tighten up your four screws. Now just throw your interior panel back in and you're good to go.And that's gonna wrap up this review and install of the SpeedForm GT350 Style Track Pack Rear Spoiler for your '15 to 2020 Mustang. Thanks for watching. For all things Mustang, keep it right here at
