Wheel bore is reamed perfectly round and smooth.
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 weight of the wheel is reduced by removing excess plastic from the underside of the wheel tread and the inside wheel face.
The inside wheel hub is lightly beveled to reduce contact with 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.
The beveled hub reduces the braking that occurs when the wheel hub contacts the car body.
