Louvers have a long history with Z-cars. They don't look good on every car, but the cars they look good on, they look really good on. Generally, the more horizontal the rear window, the better they'll look. Look at a mustang vs a challenger with louvers. Mustang looks way way better.
>>25471071>They're also a pain in the fucking ass to keep clean.FUCKING this holy shit. some old dude at autocross said the old 280ZX had them on a hinge so you could clean under them. Mine are stuck to the window with brackets and VHB, and they're a PITA to keep clean.
