Abstract: A go cart racing frame comprises a chassis having a right front portion, a left portion, a right rear portion and a left rear portion and having left and right sides, an independent seat frame for supporting a seat rigidly connected to the chassis at a plurality of weight-bearing points, and a seat frame restricter for restricting downward movement of the seat frame with respect to the chassis. The weight-bearing points concentrate the weight of the driver positioned in the seat at the left front portion and right rear portion of the chassis. The seat frame restricter forms an additional weight-bearing point when downward force is applied to the seat frame for helping to support the weight of the driver and distributing it to the left rear portion of the chassis. However, the restricter allows upward movement of the independent seat frame.
