Lateral supported wheels or g-rings will not be allowed. Maximum width of rear track at widest point is 55 1/8” unless specified under class structure or supplemental rules.

G-113: Wheel Weights: Wheel weights are allowed with each piece not to exceed ¼ ounce. Placing duct tape over weights to secure is suggested for extra safety.
