After the first two TUDOR United SportsCar Championship events, there have been several adjustments made to the IMSA Rule Book and Race Control. Here’s the quick recap:
Changes coming to IMSA Race Control include the following:
- Enforcement of an IMSA rule requiring the display of the car’s number on its in-car cameras.
- Upgraded video review equipment to high definition (HD).
- A new system for cross-checking cars and drivers involved in on-track incidents.
- Addition of a third driver advisor to work alongside the IMSA Race Director and two driver advisors to assist with evaluating responsibility in incidents and other on-track situations.
IMSA also is adjusting its full-course caution procedures to maximize green-flag running time. Changes to the procedures, which will be confirmed by IMSA Rule Book bulletins, are as follows:
- At events where there is only one prototype class in a race, the pits will be opened for that class when the field is packed up and while GT cars are still performing the Pass-Around procedure. This change will expedite the full-course caution process by a full lap.
- The “Lap-Down Wave-By” procedure – which provides a strategic opportunity for cars a lap or more behind to gain a lap back by staying on course while leaders make pit stops – will be more limited in its application. There will be no Lap-Down Wave-By in races less than two hours and 30 minutes in length. For races between two-and-a-half hours through six hours, the Lap-Down Wave-By will be used only once in any 90-minute period after 60 minutes from the start of a race. No Lap-Down Wave-By will be used in the last 30 minutes of a race.
- Efforts also will be made to use “Debris Yellows” where a situation is likely to involve the simple removal of debris or the flat-tow of a stopped car to a safe location. A Debris Yellow includes the Pass-Around procedure, but the pits remain closed until the race is restarted.
