I think 1st gen Vipers are as scarce as hen's teeth in this area.
...................If you have one, and would like to bring it to the track, I am organizing an HPDE April 16th.
This is the first of 6 events for the 2016 season.
Non-competitive / low pressure / easy going. Priority is FUN, but above that, Safety.
If you haven't done this before we have helmet rentals available.
We also have Driving Instructors to help you get around the track and keep it out of the weeds.
PM me if you'd like more info about this, or any of our upcoming events/schedule.
