Weight and Appearance
Remember, the official scale may not weigh the same as yours.

1. The car shall not exceed 5.0 ounces. The reading of the official scale will be considered final.

2. No liquids or loose materials of any kind are permitted inside or on the car.

2. Details such as steering wheel, driver, spoiler, decals, painting and interior details are permissible as long as these details do not exceed the maximum length, width, height or weight specifications.

3. Cars with wet paint will not be accepted as this can damage other cars, race equipment and the building where we are racing.


Hint: did you know that 25 United States quarters is equal to five ounces?

1. Get the weight as close to the 5 ounce limit as possible. Some folks even use a coin taped on to the bottom or rear of the car for a last second fix up.

2. Everyone has an opinion on where to put the weights. Some believe that the weight needs to be predominantly in the rear so that gravity can act upon the weight further up the incline and for a longer period of time. A car with more weight to the rear generally grabs more speed down the slope. Many suggest having the center of gravity at 1 to 1-1/2 inches in front of the rear wheels. But be careful not to put too much in the rear or you'll pop a wheelie.

3. What kind of weights to use? There are many types and styles of manufactured weights. Tungsten is probably the heaviest metal, allowing a smaller amount of weights used, but it comes with a higher price. Lead is typically not used at all, due to possible toxins. Zinc has been a popular replacement for lead, but is much lighter so more would be necessary. But this is a car race and some folks just use BB's, nuts & bolts, fishing weights and we've seen coins used. In the end, weight is weight. However no movable weights are allowed, they must be attached so that they can not move.

4. Some like the round weights found at the hobby shops and craft stores. This allows you to stick the weights out of the back of the car where you can paint them and tell everyone that they are jet engines or tail pipes.  What they really do is allow us to get the weights as far back as possible, especially if the front of the car is heavy.

5. Keep the weight low on the car and in the longitudinal center (Left/Right of the car). Put the weight just in front or behind the rear wheels for less wheel chatter.
