The phrase describes the compatibility or interchangeability of wheels or hubs sharing a selected configuration. This configuration is characterised by 5 equally spaced bolt holes organized on a circle with a diameter of 100 millimeters. Figuring out if two elements share this specification is essential for guaranteeing correct wheel fitment on a car.
Adherence to constant specs on this facet of car design provides quite a few benefits. It streamlines manufacturing processes, simplifies aftermarket components choice, and contributes to car security by guaranteeing wheels are securely mounted. Traditionally, such standardization has advanced to satisfy the calls for of accelerating car manufacturing and the necessity for interchangeable elements.
