If multiple weigh-ins are allowed, make the care heavy. Weigh it,

I've done my share of drilling to get derby cars under the weight limit,
but if possible, I recommend that you avoid this technique. It can damage
both the finish and the wheel alignment.

Another possibility is to use small wood screws for the last bit of weight.
Then remove one screw at a time until you're under the weight limit.
