    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.

    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.

    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.

    IdesOfMarch23

    • 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.

      Speedform louvers.

      I went with the aluminum louvers instead of the PVC plastic ones due to the very high heat here in Vegas. Install was straightforward. I took my time and used some clear silicone atound the mounting harware that attached to the window, just to be safe. No rattling at speeds over 125 mph. Also, no rattles at normal speeds and on surface streets. I figure why take a chance at warping in high heat, go for the aluminum.

      For Speed Limit Only!

      -These came on the used '08 Bullitt I bought. Driving to CA last summer from CO they seemed fine, and I couldn't believe how much they kept the temp down inside the car...that's a score right there! After going through 20mi of construction on I-80, I wanted to get around the trucks that had stacked up during the low speed area before they started that nonsense of jumping out into the fast lane because they were going .00002 mph faster than the truck in front of them. I ran through the gears heavily, and when I hit 110 all heck broke loose: the harmonics of the air passing over these louvers at that speed caused them to 'buzz'...scared the daylights out of me, and I thought the back window was going to shatter. So I guess they're my speed control now. -These louvers don't work in automatic car washes for two reasons: the drying fan's forced air gets under them and they rattle for the same reason as they do by going fast. The other reason is that the corners where the horizontal fins meet the side strap come to an angled point, and those shaggy styrofoam-type filaments get stuck in there, tear off and are wedged in -tight-! You need a small dental pick to dig that stuff out. -Yeah...taking these on and off by yourself is a pain and I only made that mistake once. When you pick them up off the ground, they get flimsy and sag...so right off the bat your pin holes are not perpendicular to the pins making alignment a challenge. By now you're holding these things at arms length with your buckle scratching the trunk, you want to set the dang thing down because you're not hitting one hole out of six and you're wishing you didn't have so much pride that you didn't call your pal to help! During one attempt I thought I had a pin made and slacked off...but the louvers slid off to one side, and now I needed to buy touch up paint. These louvers fit the footprint of the window with little to spare, so any little jiggle like that and you're fixing scratches...and that sharp aluminum cuts deep!

      Perfect Old School

      If i say they're old school, i know. growing up in the early 70's there was a guy down the st with a 70 Mach1 that had a Louver just like these, though a bit thicker aluminum, but it was the 70's! Everything was thicker! Wicked bad azz and mean. just like a witchy women

      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.

      installment of the back window louvers.

      I do not believe that if you used the instructions that you will be able to line up the quarter screw with a hose to the aluminum louvers. I assembled the Louver complete lined it up with the windshield masking tape all corners but the right corner disassembled the metal and cleaned the glass replaced the metal with the 3M tape and Press in place one corner at a time and all my screws have lined up.

      2017 aluminium rear louvers

      I purchased these louvers 7 months ago right after buying my GT. Out of the box, the louvers look great and sturdy which is why I went with these over plastic. Hardware kit should of been painted black. I was not to happy with the 6 exposed acorn nuts which makes theft very easy. Now for the bad....within 7 months, the black finish has started to peel and chip of during washing. It's getting to the point where I will need to strip and repaint it. Im giving this 4 stars for looks but only 2 for finish longlevity
