Review & Install Video

Hey, everybody, Justin with AmericanMuscle.com here with my quick review of the aluminum rear window louvers, fitting your 2015 and up Fastback Mustang. So the term retro is one of those words that gets thrown around a lot when describing a specific Mustang part, almost to a fault, but if there was ever one mod or product that really, truly defined and embodied the term retro, it's a set of rear window louvers. Now, when looking at this, try not think mid-80s F-body or IROC-Z, but rather, think about the '69 to '70 Mach 1 or Boss 302, where the rear window louvers made their debut on the Mustang. So basically, what I'm trying to say is if you're into that old-school look, you want to evoke that old-school flavor on your S550, then this might just be the part for you. Now the big question is, does that retro look really work on the new sleek chassis of the S550? And in my opinion, guys, at first glance, yes, it does, and I think a big portion of that is due to the Fastback design. When installed, the louver really doesn't look out of place, and actually looks pretty low-profile from all angles. I do have one nitpick though, however, and that's the amount of dead space that's located between the louver itself and the top of the trunk lid when installed. Now, if you look at MMD's plastic version of the rear window louver, I think it does a much better job of covering the entire back window, but again, their louver is a completely different design, much more modern when compared to the aluminum one I have with me here. As for the build, we are again looking at that durable and light-weight aluminum. For the construction, it has been finished off in this matte black powder coat, as you can see, but just a quick heads-up, guys, this thing is paintable, so if you did want to have it color-matched to your ride, just for a different look, that is something you could do. Now let's quickly touch on visibility because I'm sure a lot of you guys watching at home are probably wondering, "Will this thing impair my vision?" And honestly, yes, you can expect a slight impairment, obviously, because this thing pretty much is covering your rear window. However, with that being said, it's not as bad as you might think. In fact, we have some pretty decent footage for you here, showing your view out of the rear window. Again, don't forget you have your backup camera to work with. So at the end of the day, is it a deal breaker for me? Absolutely not. This thing is going to ship to you in a couple of different pieces, but once assembled, obviously it becomes one piece, and that's going to make the removal much easier to clean the back window, and I actually think it makes the install slightly easier as well. Now, your included alcohol prep pads and adhesion promoter are going to be the big keys here, guys, as you are looking for that strong bond. And another tip, make sure you check the trunk clearance once or twice before really adhering this thing to the back window. So just open and close it once just to make sure you're not getting any rubbing. Again, not the hardest install in the world, one out of three wrenches on my difficulty meter. A little time-consuming, but just take your time and you'll be all wrapped up in an hour or two from start to finish. All right, guys, to wrap this one up, if you are a fan of the rear louver design for your new S550, here's why you might want to consider this option. Again, you are getting that durable aluminum construction. You are getting the more traditional look, and you are getting a one-piece design, making it much easier to remove and clean the back window. So be sure to check out this and other options for your Fastback S550 here at AmericanMuscle.com.

these are very nice louvers, good quality. the pads stick very well. Installation was kind of a bear by the directions, so I went rogue and did them one at a time with someone pushing down on the louver ...

Flimsy

The metal the louvers are made out of is too thin. It is so thin that when you are driving as the air flows over the louvers it causes them to vibrate against the Glass in the back window.

Will this go over window tint and stick fine , as that's the first thing I'm going to do. I pick my car up this Wednesday and I`m trying to get everything that I like all together. I had an old Mustang and it had the louvre on back window aswell as the small windows and I totally loved it. I don't really care for the plastic one as its not straight across , kinda droops lol

Brent

  • Hello! Generally speaking, most window tint is going to be applied to the inside of the window, so you shouldn't have to worry about the SpeedForm Aluminum Rear Window Louvers sticking. If you are having tint applied to the outside of your window, you should consult with the tint shop about applying these louvers.

Can this be made to be more secure? Seems like anyone can just walk up, undo 4 thumb screws and walk away with it...

dana

  • The mounting brackets that are included with the rear window louver are designed to keep the product secure and mounted to the vehicle when installed. You may be able to find another form of brackets you can use for this rear window louver but would not recommend modifying the brackets included as they will be most secure as designed by the manufacture.

This is a very tempting mod. If I don't like it, can it be removed without a trace? I'm leaning toward the metal one--I think it looks cleaner.

  • The Aluminum Rear Window Louvers are removable. The mounting brackets on the rear window are held on by double sided 3M tape. Once removed from the window, the window can then be cleaned to remove the adhesive residue left over.

I'm on the fence between these and the plastic ones. I like the look of the plastic ones more but i feel like aluminum is a better choice for durability. Any input?

anon

  • This have a great durability, I was able to take mine through the blowers at an automatic car wash and all. They didn't bend or pop off. However I cant speak for the MMD set. I would imagine they are just as durable. The only issue I could foresee with the MMD set is the sun maybe causing a crack in the hard plastic. So I would go with whatever you feel looks best.

Would it survive an automatic car wash or need to be removed each time?

  • Remove it. But you shouldn't be taking a new car through an automatic wash anyway.

    these are very nice louvers, good quality. the pads stick very well. Installation was kind of a bear by the directions, so I went rogue and did them one at a time with someone pushing down on the louver to hold it in place. once i got two on the rest were easy. they make no noise and they do not move or flap going down the road.

    Great "Old School" look

    Very happy with the "Old School" look these give to my 2015 GT. Takes me back to growing up in the 60's and 70's, when you saw these on so many Mustangs cruising around. Found the instructions fairly clear and easy to follow. Just remember cleaning and prep of the glass is VERY important, as is sealing the edges of the pads and waiting the full 24 hours before final install of the louvers. The install went fairly well even though I was in the position of doing it by myself with no helper. Was just a matter of taking the time to check and double check placement, using masking tape with alignment markings on the car and louvers, sticking down one side, loosening the nuts on that side and then lifting the other side just enough to remove the backing on the tape for the second side. It CAN be done with one person if you are very careful and take your time but would have been a lot easier with two. Once the pad adhesive was allowed to cure and I put the louvers back on, the finished look is AWESOME! Looks especially good with the 1/4 window louvers I also got to go with this kit. Should help keep the interior cooler on hot, sunny days too. Once on, I drove on the highway and only got to a bit over 70 but ZERO rattle and rear vision is only slightly reduced. Not the cheapest louvers out there but appear to be very sturdy and well built and have a great factory matte black finish, which looks great with my Ingot Silver GT. Should last a very long time, would recommend to anyone also wanting this look.

    Love the retro look! Sturdy when put together. A little challenging to get the plates lined up perfect, but once installed as directed, they seem very well attached. No wind noise or rattles including on the highway. Would definitely buy the same ones again.

    Nice look

    Let me start by saying the louvers look great. The materials and quality are very good. The devil is in the details however. The mounting plates do not come painted, and they should. The nuts to secure them are PLASTIC! DOR $500 I think you should get black acorn nuts. Installation is not hard, but you need to follow directions, and measure carefully. Also while some reviewers did it solo, I think you need two people.

    Worth It!

    Was really liking the retro look and this product seemed like quality compared to a plastic louvre. Like anything; you just need ot take your time and be patient in assembly/prep work. Very nice and clean install once done. I'm very happy with it and no regrets. When you first assemble the bottom and lower louvre, before putting on the metal strap brackets, I decided to install a small bolt and washer to keep the two sections tightly together. There is already a pre-drilled hole in the middle of the main support bar that runs between the top and lower section upon inserting them together. I used a razor to remove just enough of the 3m tape for the middle bracket to allow space for the mini bolt I put through mine. Hopefully this makes sense once you see yours and start assembling it. Good luck and Enjoy!!

    Love the look!

    I personally prefer the look of these over the MMD louvers. Gave my car a retro modern look. Looking at them from the back and the sides they look very aggressive and durable! Easy to remove also to wash the window. All in all I think it's a good product. Instructions are kind of weird but with a little common sense you get the idea and shouldn't have much trouble getting these installed on your ride. Gave the rear end a whole new mean look.

    Retro Louvers

    I have had more compliments on these Louvers than anything else. I considered the plastic Louvers by MMD but if you are truly looking for the retro look then look no further. It was a fairly easy install with two people but you may as well throw the instructions away. They aren't very helpful when it comes to place the hold downs on the glass. It also makes it a bit harder to clean the rear window but well worth the effort.

    Retro Look

    I bought this for the retro look which is great. Directions were not the greatest but OK. Remember to make sure trunk lid is clear. The only down side was that I took this through a car was after it was installed and ever since then it will make a noise while driving. This was my mistake because it is very easy and fast to take off.

    Aluminum Rear Window Louvers (15-16 All)

    First; the installation was very easy, the instruction were very clear. The packing and shipping was done very well to prevent damage during shipping. Just recently installed it on car and already getting compliments on how it looks on car. Person say it takes they back to the 1965 and 1966 looks. For those of you that install it yourself, don't forget the to seal the center clip it is something that is easy to forget. Don't forget to seal around the mount bracket to prevent rain from causing them to come loose over the long term, another thing that is easy to forget too. Again I love the look and style it give my new Mustang !

    Fantastic addition to styling/looks

    As if the 2015 GT isn't already an eye catching machine...these louvers really just took it to the next level, appearance wise. They took about an hour to install. Best tip for install: PREP IS KEY. Clean thoroughly, and follow exactly what the instructions tell you, and you'll have no issues.

    Great look, easy install.

    Great product; more retro in my mind than the ABS type. Taking care in laying out/installing adhered mounts to window a must. Once down, they're down. Only niggle is at certain speeds/wind combinations there is a slight rattle against the rear window, though it is no worse for the wear of a few track days. Overall I'm very happy with it.
