I am in the same boat as you as I ordered the same configuration (Z51 without the MRC). From what I have read so far I don't think it will matter so much if you do not take your car to the tracks. Also since I plan on keeping my car for a long time, maintenance cost was another consideration that influenced by decision (most electronic sensors seem to fail sooner or later).
