      Review & Installation Video

      Hi I’m Justin with, and I have with me MMD’s pre painted classic quarter window louvers fitting all 05-09 Mustangs. If you’re looking for a retro or styling mod that will set your ride apart, look no further than MMD. They’ve quickly become the industry leader in producing cool and unique appearance parts, for Mustangs of all ages. MMD’s classic louvers are of course inspired from the 1960’s fastback Mustangs, and thanks to the retro lines of these S197’s they look right at home here in our 07 GT. Taking a closer look at the louvers themselves you’ll see that MMD went with a lightweight and durable ABS plastic construction. The louvers were then sprayed right here at AmericanMuscle headquarters, using the same base and clear coat Ford uses on their Mustangs. Finally since these parts are painted right here in house, they’re always in stock ready to be shipped the same day as your order. Included in the package you’ll find everything needed for the install, including the louvers themselves, the detailed instructions, the 3M automotive tape, the adhesion promoter and finally the alcohol prep pads. You’ll first want to prep the back of the louvers with the adhesion promoter wherever the tape will go, after you do that simply install the 3M tape and set the louver aside. Clean your quarter window thoroughly using the alcohol prep pads, after you’ve done that remove the protective backing on the 3M tape and install the louver carefully. Doing all of this should take you about 30 minutes from start to finish. So if you’re looking to add some of that classic 60’s fastback styling to your S197 Mustang, then you’ll definitely want to check out these classic quarter window louvers from MMD right here at

        Instant Improvement

        These instantly* made my car look better. It took about 15 minutes to install and you can see what they do in the pictures. They restrict visibility a little, but you can still see out pretty easily. So far they haven't fallen off in over three months so I figure they're pretty secure. The only odd thing is that the description, video, and instructions all say that you're supposed to get double sided 3M tape, but I got more like one-sided velcro tape. AM did offer to replace it via reimbursement for purchasing double sided tape.

      I live in Seattle and of course it rains a lot and sometimes HARD. Can I get through a winter here without the rain effecting the adhesive that holds these to the windows?

      • The louvers are held onto the vehicle using sturdy 3M Bonding tape and should be able to withstand the elements.

      Helpful (3)

      Do they come as a pair or individually?

      • This will come with the driver and passenger side louver for the current price!

      Will these louvers work w/your pop out qtr. windows with out any interferances? I'm looking to purchase both items

      • No I do not think they will work because they attach to the vehicle body with 3M tape, so your windows would not be able to open.

      Helpful (1)

      My kit came with Velcro tape, reading other questions and answers these should be installed with 3m automotive double sided tape and not Velcro. Can you please clarify the tape needed to mount is not 3m velcro tape but is the 3m automotive double sided tape. Thank you in advance

      • An old design of these had the velcro offered, so it may indeed be from an old batch of our inventory. Please contact our customer service department for an appropriate resolution as they should be able to resolve this if this happens pretty easily.

      Had a pair of Quarter Panel Louvers that were attached to the side of the window and extended beyond window glass. The louvers stuck out beyond the body of my GT. Do these louvers fit in the glass frame and would they be better able to withstand washing and the weatherelements?

      • The SpeedForm Classic Quarter Window Louvers will connect directly to the glass. As long as these are properly installed, you should not experience any issues with washing or the elements.
