J...There's not enough gain to hassle anyone about it. Further, IT is supposed to be an "affordable" so if someone can loop their steering lines and don't want power steering, go for it. To force someone to retrofit a manual rack is adding cost and goes against the intent of the rules.
The wiring issue, keeping it factory keeps it simple to police and actually keeps cost down.
If you had played the "safety" card too, then you'd have covered the three favorite rationale. How about, "taking the fluid out of the power steering system prevents dangerous slick stuff from leaking on the track!"...??
