CO2 Car Specifications
By Sean Nguyenle 2014
Dragster Body
One (1)-piece, all-wood construction. Any type of lamination will result in disqualification. Two (2) or more like or unlike pieces of wood glued together are not considered one (1)-piece, all-wood construction. No add-ons such as body strengtheners, fenders, plastic canopy, exhausts, or air foils may be attached to or enclosed within the vehicle. Fiberglass and shrink wrap are considered body strengtheners and cannot be used on the car body for any reason. Decals may be used for decoration only. They may not be used to gain an aerodynamic advantage, i.e., decals cannot cover the exterior axle holes or be used to cover open areas of the body.
NOTE: For 2014, ALL wheels must be located on the exterior of the body. No “shell cars” are allowed. The wheels cannot be blocked from being removed from the outside of the body.
