The factory race department was tasked with turning the 911 into a competitive race car. Since rules dictated how far the drive train could be modified for racing, the engineers found a loophole that allowed them to lighten the car as much as possible. A short production run of 19 cars were built, before economics of selling such a specially built model came to bear.
This car was called the 911R and with it's lightweight construction, and use of alternate materials, these examples weighed in under 2000 lbs wet !
One of the unique exterior features was the use of plexiglass windows for the sides and rear. We have replicated the iconic louvered quarter windows in high clarity acrylic (lexan will NOT work for this application). The louvers and flanges, of the windows, are precision molded. Then the machine shop takes over and mills the louver openings. Finally a drip tray is glued in place.
These windows are meant for glue in application, like the originals, only. Black silicone or polyurethane will replicate the original factory look. While others have preferred the clear silicone for an alternate look.
You cannot cut down the perimeter of these windows to fit pop open or fixed oe rubber trim applications. THAT model will be available early 2015
