Skully, the AZ Cobras as a group, have participated 3 times with Pro Auto Sports:
http://www.proautosports.com/ at Firebird west and east tracks over the years. Including their driver training. It is never cheap but becomes affordable as a group. It is a fun weekend with training and running in the red group, not racing. You do learn about what your cobra is capable of. We have member drivers who help train. Mikie C has been thinking about another race weekend. Perhaps in the fall?
I, for one, have done all the racing I ever will but encourage all drivers to learn you're and your car limits.
