From the 2007 Zone 8 rulebook:
"Drivers in all Modified and higher classes and Open Cars are required to wear approved driving suits, gloves, shoes and socks. Leather top athletic shoes, leather gloves and cotton socks may be worn. If a driving suit is worn (whether required or not), the specifications are as follows:
1. SFI 3-2A/5 Two or three layer suit, or
2. SFI 3-2A/1 or SFI 3-2A/3 With the use of Nomex or Proban underwear, or
3. Any FIA approved suit."
If you run with other groups, check their requirements also.
