I don't expect any changes on this rule (because then we'd all be driving prod cars! ), but has anyone sat down and actually thought about how ludacris it is to have a plumbed heater core dangling under the dash of our IT cars?

As the build on my S2000 has brought me to this subject, I feel like such a fool for being directed to keep a fully plumbed (but plugged) heater core on a racecar where I am allowed to remove the A/C system in whole. It adds additional failure points, complexity, expense, and time... all because someone thinks that having a heater core defines the class.

Who knows, maybe heater cores contain the "good for the class" magic that is polar opposite of the "bad for the class" magic contained in original equipment style remote reservoirs.

Wait... great idea! I can prop-up my laptop on the heater core while I program my stand alone engine management!
