I am familiar with the IFS hub conversion. I like the idea but not a priority or a necessity imo. I have the spacers and thought having these complete hubs with the rotors would make for an easy remove and replace, as well as a $ savings, compared to my original thought of new rotors, all new studs and any labor expense in pressing the old out and new into my current hubs.
I spaced the part about the wheel bearings
. So, its either use my existing bearings that have very low miles, with these old, unknown races, or get new bearings, or eat what I paid for the used hub set and go back to my original plan.
