Please check on the dates for their two events and see if any one of the two works for you. You do not need a Z to attend this event. Here is a chance to drive your car to the limit to you ability and safely. You will learn more in the one/two days there then you will learn on the street in 3 years of driving your car hard.
Check out clips of my visit there last year:
