B B....don't take this to the bank or anything, but if I'm not mistaken, the hub on the 08's is much the same as those on the Vrods when they started putting the Brembo's on them. The rotor is a different size, and the rotor bolts up differently, so they are able to use the same fork to bolt the calipers to, but the rotor is slightly larger, so everything lines up. You can't bolt a new style rotor to an old wheel/hub configuration. I've not looked into it further than a preliminary look though. But, I do have an 06 SEVrod to compare to, and the hub is totally different. If I'm not mistaken, the extra brackets required to bolt Brembo's to models without the new hub are to move the caliper closer to the centerline of the old style hub/axle so they could bite the old style rotor.
