Appropriate Wheel Offset for 18" Wheels?

Tom, you still running 11.75 Cordoba rotors? How fame rail clearance at full lock? Any spacer in front with that wheel? Also are those rears 305/30/19 on 19x11's? Was kicking around do those on all 4 but im thinking the diameter might be deal breaking on the front.

Still running 10.75 stock 73+ rotors! Need to upgrade those ASAP. Keep hoping someone will make a 13" 6-piston kit for my 73+ spindles. I do run 1/2 - 3/4 inch of spacer, no problems with frame rail clearance, doesn't rub, but haven't measured it either. My rears are 19x10.5 with a +25 offset....
