Louvers are purely a matter of taste. Pros, if there are any, are increased privacy and blocking of sun to make the car a little cooler on a hot sunny day.

Cons are decreased visibility, hard to clean (louvers and windows), and subject to bending, chipping or cracking. Cleaning off of ice and snow is even worse.

To each their own. My suggestion, as always, is to spend your money on meaningful mods that will increase performance or safety or something tangible.

 

 

Would love to see a picture from the inside looking out the back window with these installed if anyone has them.

 

I like the look,but would never have another set.They are hard to keep clean and you will wipe each one every time they get washed or wet.To much maintaince for me.
