Wilwood disc brake swap

The AlterKtion uses Mustang II type spindles so it may be a little different, but mine was easy. Make sure the safety wire clears the hub. Get the right length studs before you start. My friend says to cut the rotors... I have to agree, I haven't done it yet but I know they need it.

The dished piece that bolts onto the rotor... Does the dish (the recessed part) go towards the rotor or towards the hub?
