The link below is for anyone interested in getting an idea about the track configuration of the Lightning Circuit at NJMSP. It is an in-car track day video of a stock Miata. Notice that the car carries both a driver and instructor and still manages a good bit of speed and momentum. Considering the limited power of the stock Miata, this is a respectable lap.
