Axles, wheels, and body shall be from the materials provided in the kit.
Wheel bearings, washers, and bushings are prohibited.
No lubricating oil may be used. Axles may be lubricated with powdered graphite or silicone.
The car shall not ride on any kind of spring.
The car must be free-wheeling, with no starting devices.
Axle location cannot be moved on the car.
Wheel width and diameter should not be adjusted.
Lightly sanding and/or polishing the tread of the wheel to remove burs is allowed as long as it does not reduce the diameter below the allowable level.
The wheel tread width may not be less than .275”.
The wheel diameter may not be less than 1.175” or greater than 1.200”.
The Derby Committee has the ability to measure wheels if there is reason to believe the wheels have been altered.
Cars can ride on three wheels and axles can be bent to accommodate this.
Be mindful that if a wheel is raised too high it can make the car susceptible to jumping the lane.
If a car “jumps the lane” but does not interfere with another car then the car will automatically get a 10 second time for that heat.
If a car “jumps the lane” and does interfere with another car then we will run that heat again.
If a car “jumps the lane” more than 2 times it will be disqualified.
