I have alway liked the look of the early Challengers with the rear window louvers so I got them for my 2015 SXT Plus.
Rear window louvers What brand did you buy, are they aluminum or abs and how do you like them? Any other information that you could pass along would be appreciated .
Two companies that sell louvers are E & G Classics (plastic) and Wilpak (plastic or aluminum). I don't have them on my Challenger but be warned that the fit is not very good on the cheaper plastic versions. Check out this website with product reviews. Willpak® - Aluminum Rear Window Louvers
I bought the E&G louvers and they seem to fit very well. It took some time when mounting them to make sure they were lined up correctly but the fit seems fine to me.
