Actually #07R is the only one which has those air intake ducts still present. Because they did 1995 Le Mans steel brakes, and this was the best way to do the cooling issue.
Other car was (hope I remember right!) #05R and BBA did it a bit differently doing holes in to the front bumper.
Here is #07R details about the front.
Images are my own and taken 2015 Goodwood Members Meeting. Still have to say that this #07R was one of those chassis, which I really have been wanted to see....
