Bolts of minimum 5/16” diameter must be utilized to secure weights, cotter-keyed or  double-nutted.  No weight shall be bolted to the underside of the kart.  Where weight is attached directly to the seat of a kart, a large diameter, metal fender washer must be used for reinforcement.  A maximum of 5 lbs. per bolt is allowed.  Any driver who loses weight on the track will be disqualified.  Ballast weights must be painted white with kart number inscribed.  Tape, hose clamps, ty-wraps or fasteners other than bolts are not legal for attaching ballast weights to karts.
