Bad*ss Aluminum Louvers!
The Willpak® - Aluminum Rear Window Louvers are so BA that I get excited every time I see them on my 2011 Dodge Challenger R/T. They greatly improved the look and style of my Chally. I don't know why this is not one of the first things I bought for her. The craftsmanship is superb, and the fit is perfect also. Very quick and easy install (may need two people) and the hardest part was peeling off the 3M tape (they need tabs, or you need fingernails. I used needle nose pliers and that helped). I think my favorite part is the rivet style look on the edges where the screws are, very cool looking, kinda Mad Max-like. 4 1/2 out of 5 stars.

Not So Great
This is a far cry from the old Mustang Cobras. It's flimsy, not at the right sight angle can't installed exactly because the trunk lid will hit it and it vibrates in the wind. What do you want me to say? I'd have gladly paid double the money for a properly designed and built unit.

No problems with the quality and installation. Just the length of time it took to get it.

The Best Louvers On The Market!
These must have louvers are amazing. They are of the highest quality compared to the other plastic ones on the market. The 2 piece design is great for racers such as myself who can remove the louvers at the track and pop them back on for the drive home. They are nice and aggressive, sturdy, and perfect! Would definitely recommend.
