No brake dust shields

Whats the reasoning for the '13/'14 GT500's not running any brake dust shields?

I guess the company thought it was cheaper than running brake ducts for rotor cooling.

SVT expended unprecedented effort in computer modeling the under-car airflow on the '13 GT500, in part for brake cooling. Scoops and ducts were tried, but easily the best compromise was essentially deleting the brake dust shield. Almost all of it was trimmed away, leaving only a small tab to protect the dust boot on the tie-rod end. What little is left of the dust (now heat) shield is covered with a white sticker in this photo.
