Description
Modern Styling. This SpeedForm Sport Quarter and MP Concepts Rear Window Louver Combo Kit is a simple way to add bold, modern styling to your 2015-2023 Fastback Mustang. The Rear Window Louver features an angled design that blocks the sun rays, but still allows you to see clearly out the rear window without obstruction. While the Sport Quarter Window Louvers have a open five-slot louvered chevron design that still allows you to see clearly out of your c-pillar windows.
Convenient Lift-off Design. The MP Concepts Rear Window Louver will not only give your Mustang a bold modern appearance, but with its convenient lift off design it can easily be removed for routine cleaning of your back window.
Quality Construction. Manufactured from molded acrylonitrile butadiene styrene (ABS), these Window Louvers were designed using the original OEM CAD data to ensure a perfect fit. ABS is an extremely strong material known for its light-weight, superior durability and impact resistance - making it perfect to withstand the hazards of daily driven vehicles. These Louvers are completed in a durable gloss black finish for great looks and long life.
Installation. The MP Concepts Rear Louver installs using mounting brackets that secure to the exterior rear window glass with 3M automotive bonding tape. While the SpeedForm Quarter Window Louvers are designed to install simply with the supplied 3M doubled sided automotive bonding tape. Installation can be completed in about one hour with just basic hand tools, however you should wait at least 24 hours for the brackets to fully cure before driving.
