Here's the link to the videos from the Father's Day Autocross. This was the best course I've been on so far. It was setup at Little Creek Navy Amphib Base on a hovercraft ramp. Very smooth.
Look very closely at the end of my run (long very fast lazy slalom) just prior to the last turn and you can see the spoiler deploy and then retract when I got hard on the brakes for the turn. I think it looks pretty cool.
They even put music to it this time.
