      Video Review & Installation

      If you're looking for one of the most affordable ways to slap a set of Quarter Window Louvers on your '99-'04 Coupe at home, well then look no further than the unpainted options here from MMD. The materials are going to consist of basic vacuum-formed black ABS plastic, along with including all of the 3M automotive tape and alcohol prep pads needed for the installation.Price points can hover right around 60 to 70 bucks for the pair and because there's no drilling or permanent modification needed, expect a very simple one of the three wrenches on the old difficulty meter here. And I would say about 30 minutes or so to complete from start to finish, as we'll demonstrate later in the video. Now, Quarter Window Louvers are no doubt one of those love it or hate it modifications that most owners end up going with because they really dig the retro styling or vibes they bring to the table. Now the nice thing about the quarter window category is that you're going to find a bunch of different options or flavors here on the site, as far as designs go. But I would say the MMD options here are certainly going to adhere more to that classic or old school look, compared to some of your more modern options that you might stumble across currently in the category. And then of course, there's the price, right. Right around 60 bucks here for the pair for the MMD unpainted options. So even if you're on the fence, you're not really sure about how these might look on your own ride, you end up pulling the trigger, you're not really making a huge financial commitment. But what do you see we shift gears let's touch on materials real quick. And again, vacuum form, ABS plastic, is what you're going to be looking at here.Equal parts, lightweight, and durable, and very easy to install. Now, I do also want to remind you guys these are unpainted. So, therefore, they are left in this kind of raw black material, which of course, a lot of our customers actually choose to install as-is. It's not the most finished look, I will say, but it certainly is possible, especially for the price. Now, if you did prefer more of a finished or maybe custom look, you could always grab these in a finished matte black paint job. Or we can actually grab them pre-painted to match your car as well also available here on the site.Now, one thing the site is going to recommend with these Louvers is picking up the corresponding Quarter Window Blackout decals, to hide the unsightly backside of the Louvers and that three empty once installed. Totally not necessary, of course, guys, this is just something we recommend, especially if you prefer to clean up the appearance a little bit from the interior looking out. And at the end of the day, let's be honest, these are going to totally block any visibility out of those Quarter Windows anyway. So it's not like you're going to be losing anything in that regard.But now, let's shift gears, let's talk about that installation as promised earlier and again, simple peel and stick job here. Thanks for that 3M automotive tape. Your prep is very important. So just make sure you clean that surface thoroughly. But nevertheless, guys, one of the three wrenches on the difficulty meter, maybe 30 minutes of your time tops to get in place and approve that to you. Check out our detailed walkthrough in tool breakdown right now.Items used for this installation include alcohol prep pads and adhesion promoter. I'll be getting started with our MMD Quarter Window Louver installed here guys. We want to make sure we have a very clean surface because that's the most important part here, right. You want to make sure these things stay in place at highway speeds or above. And to do so it really just comes down to your prep. So getting started the kit does include some alcohol prep pads. We're going to start by cleaning the surface around the window first, and then we'll move on to our next step.Now your three empty is pre-installed for you on the back of the Louver but it basically goes around the perimeter of the quarter window over here. So that's where you want to clean. With the alcohol prep pad done, now we're going to use the included 3M adhesion promoter. This is a very important step guys. This is going to really make sure that 3M tape on the back of the Louver has a nice secure bond to the window itself. So open this up and repeat that process.Now that our window is fully prepped, we can remove the protective backing here on our 3M automotive tape. Get ready to adhere it to your window. All right, now the moment of truth. I like to start with it kind of near the top because you can really line up your B pillar here, and the outline of the quarter window scoop or Louver. So to get lined up, just simply apply some pressure.And with that done, the driver's side is complete. Simply repeat that process on the passenger side. And that's going to complete your install of the MMD unpainted Quarter Window Louvers, again, available for your '99-'04 Coupe Mustang at home. And we hope you enjoyed this brief review in install of the louvers themselves and keep in mind more cool products and videos like this. Keep it right here to
