TNT Bomber points will be awarded in the same manner as WISSOTA points. 

Points will be awarded to the driver of the car, NOT the car itself.    

The TNT Bomber Division was created for the novice or beginning driver.
The following rules are made to make it possible for these people to safely and fairly learn the sport of  racing without the sometimes high costs associated with the sport and to let novice drivers experience racing without interfering with more experienced drivers on the track. Read the rules carefully, the TNT Bomber Division is for STOCK cars and most of the modifications allowed are for safety purposes. If you have questions, call, don't assume something will be alright to alter, etc.
