Unfortunately its not from us but it is from a fellow competitor, in a Civic no less!!
The NISMO Stuff Racing Frontier appears twice in the video, once at the beginning and once at the end. And we are only getting passed in the beginning portion. You can also see that we turn on our directional to nicely point out where we would like the Civic to pass.
Also of note is that the Civic gets stuck during an off on the track and is rescued by the sweep--So there WAS some dirt/mud at play during this event!
