AAF E46 Lexan Rear Quarter Window Conversion Kit (# 11680, 11681)




The AAF E46 Lexan Window Kit is designed specifically for race car use. This kit offers a huge weight saving over factory glass windows. We use only the highest quality abrasion resistant material so these windows will not become completely scratched the first time you wipe them down!

This kit uses tough Polycarbonate (Lexan) rather than brittle Acrylic (Plexiglass) assuring you get 5 times the quality and use compared to our competitors!  This scratch-resistant material will assure your race car Lexan windows will outlast and outshine any other plastic window kit on the market!

The two-door kit comes with an aluminum mount plate along with multiple 3D printed clamps. The clamps hold the window to the factory pinch weld very securely, and since we do not pre-drill the window, you can decide how many and where you want those clamps to be.

The four-door kit comes with all mounting hardware needed to install the kit, provided that the interior door panel is cut out accordingly. Aluminum machined brackets and supports make this kit the highest quality and most refined kit on the market.
