All Double Index cars will receive 3 qualifying runs (Time Permitting), #1 Qualifier will be determined by the closest run to the 8.60, 9.60, or 10.60 index without going quicker. In the event of 2 or more cars running the same qualified ET, the driver who posts the time first will be awarded with the qualified spot. If you run quicker than 8.60/9.60 Index on all 3 runs, you will be placed at the bottom of the ladder for eliminations. If a racer misses all qualifying sessions, they still can be placed on the bottom of the ladder if the driver notifies WCSA Officials prior to Eliminations.
All drivers must stage the car on his/her own without the assistance of a crew member (You will be disqualified by the starter if you have assistance). Deep staging is permitted but not recognized by the starter (if you want to go deep it's on the driver) Auto-Start will be on.
Double Index does not allow burn-outs across the starting line. You must complete your burn-out and stop without crossing the starting line.
During 1st round of elimination's the higher qualified car will have lane choice.. In the 2nd round and beyond, the driver that is closest to the Index without going quicker will be awarded lane choice. If both drivers go under the Index, the driver that is closer to index will be awarded lane choice for that round.
All Triple Index entries are allowed to tow to staging lanes and back to the pits once the car exits the racing surface.
