What Major Sanctioning Bodies Have to Say about Weight and Weight Distribution: NHRA

Image courtesy Wikimedia Commons Weight is strictly enforced in all NHRA competition classes, with weight requirements and limits varying from class to class. The hard and fast rules that stay the same across all classes are: • any weight added, ballast, may not extend over the front or rear of the car’s body or tires, and • must be permanently attached to the vehicle, and • there may be a maximum of 500 lbs ballast with a maximum of 100 lbs of that being removable. NOTE: This information is from an NHRA Rule Book 2019 Addendum. The full rule book is only available to current members/racers. The sanctioning body for most off road racing events (like Baja) is SCORE International. Each class has a minimum and maximum weight limit. Roll bar/cage requirements also vary based upon vehicle weight. On top of this, SCORE has one rule regarding weight that applies to all classes: • Any ballast used must be installed as an integral part of the vehicle’s structure.
