If you're curious how the M2CS Racing routes brake cooling up front, this diagram will help.
The two lighter grey items are what grab the air from the front bumper with the small duct (the one you see on as a visible addition on the CS R) feeding ducting that cools the backside of the caliper/pads. Interestingly enough, the only time I've seen one of these cars in person, the lower bumper ducts that move air to the center of the disc, were blocked off.
