***4.5" to 4" redrill?***

I believe the center hub register is larger on the 4.5 rotor than the KH 4 pattern rotor.

Copy that! What I was thinking...use the whole later setup and just redrill the 4.5" later rotors to a 4" bolt circle. Can the center register on the 4" BC wheels be opened up a bit?
