    6         All weight and accessories must be securely fastened to the car, and fixed in place. Wheels are the only allowable moving part on   the car.

    12.1      Axle flaws may be removed and the axle shaft may be polished. The axle head may be   beveled on the inside to reduce contact with the wheel. No other modifications are allowed.

    21         If a car leaves its lane, and the race officials determine that a fault in the track or starting mechanism did not cause the incident, then:

    23     If no car reaches the finish line, the finishing places will be determined by the distance traveled by each car in its own lane.

The repair must be completed within the longer of (a) five minutes, or (b) the start of the next heat in which the car will run. At the discretion of the race official, additional help may be provided to the owner of the car.

    25     If a car part (other than a wheel) falls off during a race, the part cannot be replaced on the car.

    26     Any appeals or rule questions must be promptly brought to the attention of the race officials.
