Precision-molded tricky composite hub for X4 platform. Tricky composite is softer than Graphite material and thus yields more technical grip regarding vehicle and improves part traction. Suitable for low-medium traction asphalt tracks and very-low hold carpeting tracks. The hubs allow complete adjustability associated with the axle height to adapt the car to every condition. The aluminum front side steering plates and rear ARS dishes are easily mounted depending on the hub's location. The look for the hub is universal with the exact same component used at all four corners with matching extensions.
