Brian,
Just to clarify the real story behind this right from the horses mouth as we would say. I've built two versions of these protectors for myself. After seeing fellow racers almost getting severely burned both on video and in person, I decided it was time to do something. In the beginning, I was only protecting myself. However, out of the blue I received a phone call from Pink Hat as he had heard thru the grape vine I had built something and wanted to see it. He reviewed and suddenly added to rules. If he checked with INEX before implementing, you would have to ask him . Picture of my second design is attached below.
