Sometimes, we have to use a little "creative license" when going by the kit instructions painting guide. You would be ok to paint suspension arms semi-gloss or satin black. And there's much much more than flat, gloss, and semi-gloss.....theres oily black, weathered black, grimey black...etc! "Tire black" is probably a semi-gloss.
And yes, what's wrong with new cars being black?
