Yeah, probably, but don't be too suprised if they never say anything about it after you spend the money and do the install.
I've run under 6.5 1/8th for over a year now. Suddenly 2 months ago the track tech told me that if I am under 6.5 I must have a window net. I spent a lot of money to get a net and have someone weld the mounting brackets for me. Since then I've raced at the same track as well as 2 others and I've never taken the net out of the trailer because nobody has asked for it. Hell, I've seen a truck go down the strip with no doors and no net and nobody said anything.
