I believe the front chrome molding actually interferes, touches or nearly touches the rubber bumpers.
You likely are right, but may I submit another reason?
Elastomeric allows for a monochromatic look. Having a chrome nose piece ruins that look, not to mention the chrome nose piece was to create the effect of a loop bumper.
That butterscotch car at all the Flings with the Elastomeric lower and chrome upper looks really goofy (I'm trying to be polite here).
