I am attending the drivers school in April at NHIS and am trying to make the needed modifications to my wife's BMWCCA club racing prepared 1988 M3 to pass tech. Besides the fuel sampling valve, disconnecting the ABS, and disabling the steering lock, is there anything anyone knows should be done? I also have this from the NARRC rules:

ALL ENTRANTS MUST have in their possession, and available to tech personnel or the Chief Steward, the "Series Rulebooks and specification sheets" (IMSA Rulebook, SCCA Pro Racing rulebook, Pro-Rally rulebook, etc.) and an official manufacturer's shop manual(s) to authenticate the vehicle in
its state/condition of preparation.

Does anyone know where I get this stuff?

Thanks
