      Video Review & Installation

      If you're looking for the most affordable way to slap a set of quarter window louvers on your 2005 to 2009 coupe, look no further than the SpeedForm option shown here in matte black. Now, materials will consist of the vacuum-formed ABS plastic along with including all of the 3M automotive tape needed for the install for right around $30 for the pair. And because there is no drilling or permanent modification needed, expect a relatively simple one out of three wrenches on the difficulty meter here and about 30 minutes or so from start to finish. And, as always, we'll show you how it's done later in the video.So quarter window louvers, I would say, are one of those love it or hate it mods that most owners tackle because of that retro styling it brings to the table. Now, you can find them in a few different flavors as far as general designs are concerned but I would say these guys are gonna adhere to that classic or old school look more than some of your more modern options that you might stumble across here on the site. And then there is the price which, again, for right around $30 for the pair, 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 gonna be out a ton of money. But what do you say we touch on the materials and again, vacuum-formed ABS plastic is what you're looking at here, guys, which is gonna be equal part lightweight and durable. Now the finish on these particular options will be matte black which, by the way, will also be your most affordable of the bunch, but quick heads up here, guys, you can also grab these things in a gloss black or even a carbon-fiber option as well, all of which will be a few bucks more but nothing really too crazy.Now, one thing the site is going to recommend here, guys, is to grab the quarter window blackout decals on the product page to hide the unsightly back side of these guys from the inside looking out. Now, it's totally not necessary. You don't have to do it but if you're looking to keep things a little bit cleaner in an appearance standpoint, certainly not a bad idea. Now, at the end of the day, one thing you should all be aware of is that most if not all of your visibility is essentially gonna be blocked with a quarter window louver like this in place. And unfortunately, there's really no getting around that. But now, let's get into the installation. And again, peel and stick job is what you can expect here, guys. So one out of three wrenches on the difficulty meter. A few minutes from start to finish. Now I will say the most important part of the job will be the prep. So just make sure your area is nice and clean before getting started. No alcohol prep pads or 3M adhesion promoter included with this package. However, it would not be a bad idea to grab some before tackling the install. But to show you a better idea of how it's all gonna go down, here is a detailed walkthrough.Tools required for this install: a soapy water solution, a clean rag, and a razor knife. All right. So your first step is to take your soapy water solution and clean the surface that you are mounting your quarter louver to. And let that dry thoroughly before sticking your 3M tape to it.All right. Next step is to take your 3M tape and to line it up along your perimeter of the louver. And I like to leave about an eighth of an inch from the edge. Take your razor blade, make a little cut on the end here. All right. Now we install it on the vehicle.All right. So your last step is to remove the backing strip for your double sided tape and stick it on the window. Now, I like to grab it from the back side, that way I can just flip it over, line it up, stick it on. Now, you're gonna wanna hold it, hold the edges for about a minute to make sure you have good stiction. And then you're gonna repeat all those steps on the other side.All right. That's gonna wrap up my install of the SpeedForm Quarter Window Louvers. And you can get yours right here at
