Well would have to look for other series that race a C7 body style. Could search Trans-Am as a few C7s run there. Could look to SCCA T1 or GT1 class which run similar cars. Pratt&Miller are the only ones allowed to run the C7R GTE the protoform body is based off of, and they only ran it in yellow. There’s a company in Europe that makes a GT3 spec C7... Callaway I believe, and it would have run in Blancpain or SRO races in Europe, that’s where the above scheme came from.
