I have two issues to address:
1. I have a fiberglass racing seat made for boat racing and modified with a taller head rest. The rules state that I must submit a composite seat to the technical committee for pre-approval. How do I do that and who do I contact to arrange for evaluation?
From the rule book:
"All vehicles shall use a seat designed for racing. The seat shall be constructed of a metal or alloy sufficient to retain the driver under high “G” loading. Composite seats must be pre-approved by the technical committee."
2. I have an OEM laminated front windshield in a car that will run for records over 200 mph. The car also has laminated side windows and rear hatch glass. My question is: Can I run my OEM laminated windshield in a Modified car? How about the laminated OEM side windows and rear hatch glass? The rules start out talking about non-stock windows and windshields and I understand that they must be lexan. All my OEM windows have the notation that they are laminated safety glass with no cracks. Also, my door windows have a full frame all around. Please refer to the sentence that is in BOLD below: The way I read this, all OEM laminated safety glass is good to go in classes over 200 mph. What will the tech inspector say?
Per the rule book:
All non-stock windows and windshields shall be made of shatter-resistant plastic, such as polycarbonate (Lexan), and shall provide 120 degrees of adequate vision forward. On all open body cars a windshield is

recommended, but shall not restrict driver entrance or exit. In all classes where a headrest fairing is permitted, the windshield may sweep around the driver’s head and connect to the fairing on either side (refer to 3.E Driver’s Compartment rule concerning sharp edges).
All windshield wiper blades and arms shall be removed. On front and rear windows, retaining tabs or straps are required over 175 MPH.
Vehicles with T-Tops or moon roof panels shall have the panels retained with tabs or straps.
All vehicles in classes where the record is under 200 MPH shall have SAFETY film on BOTH SIDES of all non-laminated safety glass windows, or replace the windows with polycarbonate material.
All other glass, such as Glass headlights must also be covered in Safety film.
Common window tint will NOT be allowed as a substitute for SAFETY film.
All vehicles in classes where the record is over 200 MPH shall have all non-laminated windows constructed of polycarbonate material.
All vehicles with ‘frameless’ side windows, regardless of speed, must have all non-laminated windows constructed of polycarbonate material
Additional bracing must be installed to prevent window blowout or collapse.
The original roll up window hole may be closed in when replacing the frameless glass windows with polycarbonate.
Thanks for your incite..
