Today I ordered these pre-painted (Candy Apple Red) quarter window louvers from American Muscle. They should be here by Tuesday. Any input?

 

I'm curious how they attach. Looks-wise, they look exactly like Roush ones minus the three bolt holes. At least with my Roush ones I'd say make sure to apply the 3m tape exactly like is suggested and with the outside temp appropriate too. Can make all the difference between them staying on long term verses them coming off. I've never had mine come off even once.

I want a set of these for my car. But I will prolly go with the Roush set because you can take them off the car and clean behind them.

 

The American Muscle louvers arrived today. The paint quality is very good and the color match is perfect. Here are the photos of the final install.

 

Looks great ...
