Texas Region Supps
Texas Region Time Trials events are governed by our regional Supplemental Rules in addition to the National Time Trials classing. These supps provide details on how the regional program is run, how the board and its members operate, and specific details regarding the seasonal points championship.
Open wheel cars are NOT permitted at any Texas Region Time Trials events.

Classing
The Texas Region Time Trials program uses the SCCA National Time Trials classing. Visit the National Time Trials website for classing information. If you need further assistance, you can contact any member of the Texas Region Time Trials board.
I have a Road Race car. Can I participate in a Time Trials event? Yes! With some exceptions, many Road Race classes are eligible to participate in any regular Texas Region SCCA Time Trials event. Please see the list below for eligible classes and their Time Trials equivalent.
Unfortunately some classes are specifically excluded from participation because their performance significantly exceeds even the fastest of our region Time Trial cars. Additionally, open wheel cars that are not already explicitly classed in the National Time Trials rules are not eligible for participation.
- Time Trials “Unlimited 1” Class: GT3, GTX, GTA, AS, T1, T2, T3, T4, STU
- Time Trials “Unlimited 2” Class: GTL, IT all, STL, P all, SM, B-Spec, SP, SPB
- Excluded: GT1, GT2
Safety Rules
All Texas Region Time Trials events are held under the National Time Trials and Track event safety rules. Your level of required safety prep depends on your class. Details on this rule-set can be found on the National Time Trials website here.
Closed-toe shoes are REQUIRED for all classes.
Shorts are permitted, but it is strongly recommended to wear long pants.
If you car has a “half-cage” or full roll-cage, you must wear the appropriate matching safety gear (shoes, helmet, fire suit, gloves, etc) even if your vehicle class does not require it.
For convertibles, we require you to run top-up while on-track.
