Polycarbonate rear windshield allowed?


Hi all,

Does anyone have any context on whether polycarbonate rear windshields are allowed? It is explicitly stated that they are allowed for side windows, but not mentioned for the rear windshield. Since it is not clearly stated allowed, does that mean it is not allowed?

The reason I ask is because it is explicitly required for Champ Car racing, and I would like to use the car for both races. SpecE30 for personal use, and Champ Car for group racing with friends.



No. Remember the basic premise of the rules…
1.3.Only modifications specifically authorized are allowed; and competitive adjustments are not allowed. Other than the modifications specifically allowed in these Rules, every part of the car must remain as it came from the factory.
