Effective immediately, for all 400 Thunder Sportsman Championship racing, the following changes will take effect:
All Performance Brackets – Championship Qualifying Points
The following qualifying bonus points will be awarded for the top 5 qualifiers in any Performance bracket at any 400 Thunder championship event:
1st – 5 Points
2nd – 4 Points
3rd – 3 Points
4th – 2 Points
5th – 1 Point
These points will be added to the competitors total on top of any round win points achieved and will not be affected by any points capping.
All Performance Brackets – Class Swapping
Each driver is only permitted a maximum of one class swap per vehicle/bike per season. Further to this, a class swap can only be made after an engine combination change or transmission type change that would necessitate a class change.
Competition Bike – Name Change
The bracket known as Competition Bike will now be known as Performance Bike.
IHRA Australia will update these relevant rules accordingly.
