Abstract: Each of a number of wheel hubs of a modified mini stock racing car is removably affixed to a corresponding one of a number of brake rotors in coaxial relation with its corresponding axle. Each of the wheel hubs has a hollow cylindrical base portion coaxially positioned around the corresponding axle on the side of the corresponding brake rotor closer to the corresponding end of the corresponding axle than the opposite side of the brake rotor. The base portion has a first end and a spaced opposite second end axially farther from the corresponding brake rotor than the first end. A number of equiangularly spaced ears extend radially from the second end of the base portion of the hub for equal radial distances and a plurality of equiangularly spaced gussets equal in number to the ears extend radially from the base portion.
