Makrolon rear window for hardtop of the MX-5 NA / NB / NBFL from Plastics 4 Performance. The rear window offers enormous weight savings compared to the original glass windows. The window can be mounted in the hardtop using screws and a window seal. We ourselves use these Makrolon windows in some of our racing cars, where they impressed us with their breaking strength and their low weight. Makrolon windows scratch, for example, if the treatment is too rough during washing. So be careful here. We recommend a very fine microfiber cloth for washing Makrolon windows, which should not be pressed on too hard when washing. Never wipe dry over the window. This can lead to fine scratches that tarnish the window.
The Makrolon windows can be TÜV approved in our house and are therefore approved for road traffic.
