NZDRA Rule Changes/ Amendments for 2011/2012 Season

These are the changes/ amendments or additions to the 2011/ 2012 NZDRA rule book. Printing of the 2011 /2012 rule book will not take place this year due to outside influences but that will not preclude these changes from taking effect immediately.

2.20.01 Group two vehicles running on an index; All Group Two vehicles at the first national series event will have their index softened by two tenths over the national record. Any vehicle running under that index will have that index reset at the next event. Vehicles will only need to be weighed if and when they run under the current National record at which time the index will be adjusted to the new ET. The following year the index will restart two tenths over the national record as above.

Junior Dragster

Concept:

This division is intended to cater for competitors between the ages of 8 and 17 years. Racing replicas of Dragsters over a maximum of 1/8 mile. It is an introductory class intended to teach youngsters the fundamentals of Drag Racing.

The Dial-Your-Own handicap system, with breakouts is to be used. A Dial-in restriction of 7.90 seconds in the eighth-mile will apply to Seniors & 8.50 for Junior. A cushion of one tenth (7.80 Senior & 8.40 Junior) will apply during qualifying only, but qualifying times under the 7.90/ 8.50 index are deemed to be worse than all times over the index with the greatest amount under being deemed the worst. Note: Any vehicle running under 7.80/ 8.40 during qualifying will be disqualified from any further racing at that event. Any vehicle running under 7.80/ 8.40 during eliminations will be disqualified from any farther racing at that event. In the event of a breakout or dual breakout in the final round, the lesser infraction will be declared the winner.
