I saw that on ebay the other day. Then I found this.
It looks like it works great. And definitely cool. But the only thing I would be thinking after every run is "now I gotta pack that damn thing back up!".
That being said... my son would absolutely love deploying the chute, so I will probably grab one. I need an excuse to ditch the stock radio anyway.
Yah, this one is definitely on my winter upgrade list. I've already had a scary rollover hitting the brakes on a sticky track, this would definitely save the car a few times.
