Somebody please take a minute and educate me.
I thought the Texas Mile did have requirements for roll cages (see below)
Is this requirement insufficient?
********************************************************************
2. ROLL BAR/CAGE: A 4 point roll cage that meets drag racing specs is required for cars going 190MPH and higher. Some exceptions might be made for factory roll protection based on car manufacturer, experience of driver, projected top speed and special waivers signed.
3. DRIVER RESTRAINT SYSTEM – The seatbelts should be in good condition. No damage may be present on the seatbelts and they must be the factory configuration.
Any harness or any restraint system, other than factory stock, shall conform to the following in all respects* except for the expiration regulations.
1. All vehicles must have a five (5), six (6), or seven (7) point seat belt system. Arm
restraints are required in open cars and cars with: Open T-tops, Open Targa
tops, missing moon/sun roofs, or glass moon/sun roofs.
2. A five (5) point system consists of: a three (3) inch lap belt, two shoulder belts
that are either two (2) inch (for use with HANS only) or three (3) inches wide, and
a two (2) inch anti-submarine strap.
3. A six (6) point system is recommended for cars where the driver is seated in an
upright (to thirty (30) degrees) or a semi-reclining position. It consists of two (2)
anti-submarine belts in addition to lap and shoulder belts. Note: Current FIA
Approved belt sets with two (2) inch lap belts are acceptable with the six (6) point
system.
4. A seven (7) point system is recommended for seats with more than thirty (30)
degrees of incline. Note: Current FIA Approved belt sets with two (2) inch lap
belts are acceptable with the seven (7) point system.
