Hi Aus, I got the rotors for about $600.
I used a bracket to mount the caliper but could have filled and re tapped the original caliper mounting holes :shrug:
No spacers used. The inner hub offset aligned the rotor center in the caliper, mindful of the clearance of the lower ball joint,
The outer hub offset pushes the wheels out giving wheel clearance from the caliper whilst staying inline with the guard.
Needed to get extended wheel studs.
I do not think the hubs would be cheap.... I did all the specs, design and with mates rates it still hurt.
They need to be milled from T6061 hardened grade aluminium and not many companies are interested in one offs.
If it gets too hard... just order a set of these CP5570-1018.G8 8)
