      Video Review & Installation

      Justin: If you're looking for the most affordable way to slap a set of quarter window louvers on your 2015 and newer Fastback Mustang, look no further than the Speedform option shown here in matte black.The materials will consist of the vacuum-formed EVs plastic, along with including all of the automotive tape needed for the installation for right around 40 bucks. Now, because there is no drilling or permanent modification needed for the install, expect a relatively simple one out of three wrenches on the difficulty meter here, and about 30 minutes, or so, from start to finish.So, quarter window louvers, I would say, are one of those love it or hate it modifications that most owners tackle at some point because they dig the retro styling that it brings to the table. You can certainly find them in a few different flavors, if you will, here, on the site as far as designs are concerned. And I would say that these are going to adhere to more of that classic, or old-school look, more so than some of the other modern options that you might stumble across here, on the site.And then, of course, there's the biggest draw, at least in this particular case, which is the price, again, right around 40 bucks, which means, even if you're on the fence about running a louver like this, and end up not really digging the look at the end of the day, you're not going to be out a ton of money.What do you say we touch on the materials. And, of course, you are looking at that vacuum-formed EVs plastic again here. So, equal parts lightweight and durable, and again, these particular options are finished off in that matte black, which, by the way, will also be your most affordable of the bunch. You can also grab these things here, on the site, in a gloss black, and also a couple different carbon fiber options, all of which will be a couple bucks more than the matte black, but nothing really too crazy.Now, on a similar topic, one question we do get asked a lot is can you paint these things? And yes, that is totally possible. However, you would just need to get them prepped and primed before doing so.Now, one thing the site is going to recommend here in this case, guys, is to grab the quarter window blackout decals, also available on the product page. What those are going to do is basically hide the unsightly backside of these guys once they have been installed, from the inside looking out. Now, it's not totally necessary, but if you're looking to keep things a little bit cleaner from an appearance standpoint, it's certainly not a bad idea.Last, but not least, guys, and this one might be pretty obvious, at the end of the day, most, if not all of your visibility is going to be blocked out of the quarter windows with any louver in place, including these, so there's really no getting around that.But now, let's get into the installation as promised. And again, peel and stick here, guys. So figure one out of three wrenches on the old difficulty meter, and a few minutes from start to finish. Now, I will say the most important part of the job is certainly going to be the prep. So just make sure you have some alcohol prep pads, or alcohol on hand before doing so. And also, you might want to pick up some adhesion promoter from 3M, available at your local parts store, which is not included with this package. But again, to give you a better idea of how it's all going to go down, here is a detailed walkthrough.Mechanic: Tools required for this install are a soapy water solution, clean rag, razor knife. All right, the first step is we're going to take some soapy water and we're going to clean the surface that we're going to be mounting our louvers to. You're going to make sure you allow this to dry completely before sticking your double-sided tape to it.All right. So the next step is to take the double-sided tape and to go all the way around the perimeter. Now, I did prep this as well, just with that same soapy water, and allowed that to dry thoroughly. So let's get started with the double-sided tape.And if you have a razor knife handy... I'm going to repeat that for all four sides. I'm leaving about an eighth of an inch of reveal on this side, and up here. Small piece here.Okay, so the next step is to remove the backing of the double-sided tape. You're just going to peel back with your fingernail. Then flip it up. Grab by the inside of the louvers, and you're going to want to pretty much evenly line it up to where it is going to place, and it fits perfectly in here. And you're going to press firmly all the way around, and you're going to want to hold it there for about a minute, or so, just to make sure that that double-sided tape sticks. And you're going to repeat all those steps that we just went over on the passenger side.All right. That's going to wrap up my install of the Speedform Vintage Quarter Window Louvers.
