These changes do not impact the 2024/25 season, including the remaining 2025 local races, rallies or the World Championships in Akron on July 19.
Changes effect master build plans and rules governing wheel swaps. The ISBD is getting the word out sooner so participants are able to plan for next season.
The changes for the new 2025-2026 season are:
- Masters Build Plan addition – stipulates that the six (6) elevator bolts in the rear of the master car may be epoxied in the floorboard of the master car. The epoxy must not extend above the top surface of the mounting plate or on the threads, washers, or nuts of the bolts above the top of the mounting. If using a second plate must be easy to remove. (See photo for allowed epoxy area details.)
- New wheel swap rule – allows for a third type of wheel swap: 0/4/0 progressive with an initial wheel bank provided by either the race city or pool of wheels. Read the new wheel swap rule change
If you have additional questions, we encourage you to work with your regional directors.
