Purchased these from ECS Tuning for $43/pair. They're listed as "997 Turbo Rear Brake Cooling Duct Kit". Part number 997-331-487-02KT.

Attached are some cell pics of the mods/trimming I did to them in order to get them to fit without rubbing or scraping anything when the wheels are not fully dropped (like they would be on a lift; slight, non harmful contact between the plastic and surrounding material when wheels are at full droop).

I did not need to trim the rear brake disc shield; air would be directed onto the disc and into the rotor hat with no modification. I could have trimmed an inch or so... Maybe less.... But it wouldn't have mattered for me as this is a cab (and not a track car).

However, cool brakes are happy brakes. And, here in central Florida, I do like to bomb some back roads and they can get quite hot. I already have GT3 cup (the $30 polymer clip on) brake ducts on the front brakes and they keep the pedal feeling quite hard, whereas the pedal could gain a softer character after a half hour of hard driving with the OEM 996 front brake ducts.
