I got them installed yesterday and I am looking foward to my next trackday in August 23.

The air guides are absolutely functional by design and application, which happens to be the same as on the Porsche 911 GT3 they were designed for. Many others on this forum ( @

I don't think anyone has done any controlled testing of the guides to determine rotor temperatures with and without them, but the general response from people who use them is positive. They are cheap and easy to install so I think you'll see more people using them in the future.
I installed the GT3 air guides at the same time I installed my big brake kit so I can't really tell you to what measurable degree they are working because I don't really have a good point of reference. I can tell you that around Atlanta Motor Speedway (a road course + oval) a couple weeks ago my brakes performed extremely well and they cooled off so much going around the long banked oval portion of the track they had significantly less bite going into the first corner, so I had to brake extra early to get heat back into them. This was likely attributed to both the excellent thermal efficiency of the BBK and the air guides helping them out as well.
I'm running the car at my home track this weekend, Road Atlanta, which is much more braking intensive. I should be able to really give the brakes a workout and experience their full potential.
