Sorry, I have to rely on what I'm given, I (regrettably) don't own one of the twins.
The fans are mounted to two of the wheel bearing attachment bolts that I have drilled and tapped for small screws.
The air enters the fan in the center of the spindle and over the caliper mounting boss of the forging and then is directed down to the caliper pistons.
Above is a picture of a fan mounted in a similar arrangement for a 350Z.
Although the OEM floating caliper is ideal for this by having all the pistons right in the focus of the airflow,
I'm having good results on the 350Z and the STi's fixed calipers too.
The STI and many others can use a strut mounted housing to hold the fans.
I hope this helps explain it better.
I plan to have some better pictures after this weekend's tests.
