The XRAY X4 Graphite Composite Hub is a precision-molded Graphite composite hub for X4 features new suspension geometry for improved steering and traction. The hubs are compatible with the updated drive axle that moves the driveshaft pivot point deeper into the hub, in line with the hubs rotational axis between the upper and lower arm. This alignment improves driveline efficiency and handling.
The hubs allow full adjustability of the axle height to adapt the car to every condition. The aluminum front steering plates and rear ARS plates are easily mounted depending on the hubs location. The design of the hub is universal with the same part used at all four corners with corresponding extensions
