1. GN Light Modified division weight limit is now 6200 lbs. for 2023 season.
2. Super Farm, Light Pro Stock, and Limited Pro Stock divisions cannot enter the new RN Heavy Pro Stock 5.0 class. Entering of stated vehicles in divisions other than RN Heavy Pro Stock 5.0 as permitted by 2023 NTPA Pulling rules is still allowed.
3. The WPI Executive Board moved to limit Mini division at all levels to any current 18.4×16.1 – 6 ply tires already in competition from 2022 season (Pioneer, Cepek, Mayhill). No changes to construction or dimensions of these tires will be allowed for the 2023 season. Limiting Mini division to these tires will maintain current vehicle dimensions and weight limit while keeping competition at an already high level.
