Inner hub face is squared to ensure accurate mounting on the CNC lathe.
The wheel tread is lathed to achieve a perfectly round wheel and a flat tread surface.
The inner edge of the wheel is trued and the molding mark removed.
The weight of the wheel is reduced by removing excess plastic from the underside of the wheel tread and the inside wheel face.
Both inner and outer wheel hubs are coned to reduce contact with the nail head and the car body.
Round and smooth wheels roll faster than standard wheels.
The weight reduction provides a faster start, and improves the balance of the wheel for a smoother ride.
