Within IKF, the 60 inch rule came into effect in 1965 and lasted until sometime in 1969. The rule was made to try to limit laydown karts and how low a driver could be positioned, but it affected all karts racing with IKF rules. IKF eventually realized that builders re arranged the seating area to make it possible to lay down, but with your legs folded up into an uncomfortable position. In 1969 they finally allowed the kart lengths to go up to about 65 inches and then not long after they allowed even longer lengths. I can't find any info in my older magazines or GKCA magazines that showed a rule making sprint karts so short and uncomfortable. It seems like builders just followed the example of others and kept making short leg room karts. Up to 1965 IKF allowed karts to be about 65 - 66 inches in overall length. A racer from Oregon or Washington named Larry Eyerly usually gets credit for one of the first laydown karts with the driver laying fairly flat. After the 60 inch came into effect he built a new kart compliant with the rule and still lay as low as he did in the first kart he built.
Are you referring to the front bumper foot guards for karts with your feet in front of the front axle? Those guards/upper bumpers became a requirement around 1975. I don't remember the exact date. A lot of us didn't want to put them on, but they turned out to be a good idea.
