The Corvette Group and Bondurant has a relationship that's already established. Plus it helps that they already do things such as Corvette's on Bondurant every year and Johnny O'Connell is such a Corvette Enthusiast. (I am posting up the flyer for the Corvette's On Bondurant event that Johnny O'Connell does every year, it is not for this Autocross event)
ATTEN: THIS FLYER IS NOT FOR THE AUTOCROSS EVENT! Its a reference for the above explanation.
I am not saying its not possible it does happen but having that ground work already in place really helps.
It is certainly something that can be worked towards but for now this one is already setup and happening and they have opened up for others to join in. You have some time to plan a head and join in on the fun. Then from there you can see if something can be arranged for a meet directly tied to the AZ86 group if you like.
