#1032 "Not exactly eyebrows"

Original image shows added door guard that can't be described as eyebrows but surely something holman/moody added to the car. Any thoughts why, what it's made of and was it unique to that car and that race?
Thanks guys

It looks like just another design of 'eyebrow' to me, typical of a race team experiencing a problem (door lift at speed) & coming up with a quick fix.
