VIDEO: Brake ducts installed at VIR!

Here's one of those videos that rely on just one viewpoint that's so amazing to watch that it doesn't take much to keep it interesting.

I have had a hard time keeping my Ford Fiesta ST in brakes during track events. The ST is hard on them, because it actually uses the brakes during acceleration out of a turn to keep the inside tire from spinning. It's called Torque Vectoring, or sometimes it's called an "e-diff". 

My hope was that keeping the brakes cooler would reduce the rate of wear, so I built some brake ducts. 

The ducts just provide some additional fresh air right to the hub area, where hopefully the rotors will pick it up and flow it through their cooling vanes.

I put a camera down there to see what was going on with my design, and I was pleased to see that the system worked better than I could have imagined. The evidence is how quickly the red hot rotors go dark again.

but the video is even more interesting, just to watch everything mechanical going on.. The engine shifting, the suspension compressing, the tire stressing. It is pretty interesting to watch.
