The rotor would have to bolt onto the face of the hub,
The inner and outer bearings are spot on and the offset from the hub face to the spring perch is pretty much identical from the original hub to the aftermarket 5-lug hub,
These new 5-lug hubs are supposed to be good for 500kg a corner and my engineer has said they should be okay but might be an idea to use stronger studs, he hasnt seen it yet though,
