Vertex Polycarbonate rear glass (4mm thick) with weatherproof treatment on both sides

It will be a polycarbonate rear glass (4mm thick).
It is a polycarbonate rear glass that has been specially cut, R-processed, and weather-resistant on both sides.
We have extracted the 2016 regulations of the drift race categories "Formula Drift" and "D1 Grand Prix", but currently many race regulations do not allow acrylic glass and require polycarbonate.
By setting the thickness to 4mm, it corresponds to most races.
Also, by changing to polycarbonate, it will be about 50% lighter.
