Race Class Information

Shannonville Drags Bracket Series



Driving past the starting line, under power, after your burnout is PROHIBITED. Do your burnouts then proceed to stage. The only EXCEPTION is cars with no front brakes.

Once one car has lit the pre-stage bulb, both cars can only move in a forward motion. NO EXCEPTIONS. The last staging motion must be forward.

All drivers are to proceed to stage in a timely manner. This rule will be strictly enforced by track officials.

Auto-start to be used.


There will be a full refund for any racer who breaks before Round 1. Any racer whose race vehicle breaks before Round 1 must come to the registration tent and inform us before their Round 1 is called to the lanes. Failure to do so will result in the racer not receiving a refund of their tech card money.


  • If a class has completed its first round of eliminations, the race will be considered complete and the purse split among round winners.
  • If a class has not started or completed its first round, tech card money will be refunded 100%.
  • If a class cannot complete the current round of competition, payouts will be split based on the previously completed round.


Your dial-in is to be on your car before you cross the ready line. Once the lanes director signals both paired cars to cross the line and one car crosses over, dial changes are PROHIBITED for that race.


Tech cards are to be purchased at the registration tent.  Tech cards are only to be sold to the racer entering the event.

All race vehicles MUST be teched and tech cards must be handed to the tech inspector.


Any protest MUST be made before you stage your car.  It is the racers responsibility to make sure that their dial-in is on the board correctly and that any mechanical malfunctions that might be in question are addressed prior to staging. Once you have staged, you have “agreed” that all things are okay including dial-ins for both lanes, staging beams and any other item that might factor in to make you “race ready”. Should you have a question about anything, DO NOT STAGE. Get the attention of the starter and address the problem.


When a class is called, head to the staging lanes.

If you want the LEFT lane use Lane 1 until full then Lane 3.

If you want the RIGHT land use Lane 2 until full then Lane 4.

In the event of uneven pairings, we will empty the lanes in pairs and then pair the cars in the same lane.  The first in the pair will get lane choice.


Buyback cars will return for Round 2 in Lanes 1&2.

Round 1 Winners in Lanes 3&4.

The ladder starts at Round 3.


Round 1 is a random pull. Will hold to the end.

Round 2 is Best R.T. from Round 1
