another interesting spoiler - the 1999-2000 Honda civic Si had a DI spoiler that was installed by default at the dealership - buyer could order a car with a delete. as most all of the cars have this, and it was not an "option" per se, how would you rule on this in ITS?

another - MkI MR2 (85-89) is allowed to run the aero kit (skirts, rear window fin, front spoiler) per the spec line. the aero kit did not exist in 1985/early 1986 but the spoiler alone was an option. could an 88 car (different nose, engine air inlet) run just the wing without the skirts or other parts of the kit? could an 85 car run the skirts and wing but not the window fin? I figure the front plastic spoiler is moot with a legal air dam installed.

MkII MR2s were VERY rare in the US without spoilers, but they happened. there was a "1990 MR2 coupe" in the UK with NO wing option.
