Add the distinctive performance look to the rear window of your ride with an Astra Hammond aluminum or ABS louver - a product line that offers the broadest coupe and sedan applications, over 120 different models, from the mid-60s to today. Rear window louvers were all the rage in the muscle car scene of the 60s, 70s, 80s, and now you can have the same styling for today's performance coupes and sedans. They will visually enhance the performance look of your car while increasing privacy and minimizing interior temperature. Most vehicle's applications are available in a matte-black aluminum, black textured ABS or a smooth black ABS finish. The smooth black ABS louvers must be painted and can be ordered to match your car's color using their paint program. Installation and attachment is now easier, and less invasive than ever. Depending upon the vehicle most of their louvers attach with stainless steel hardware, or with 3M double-sided tapes, and others with dual lock tape or under the trim.
