Thinking of either renting a seat or buying a car & racing IMSA GT4. Unless someone wants to gift me $10M a year to race prototypes LOL
Unsure of seats with the teams running official Clubsport cars in GS (eg. CJ Wilson), but Rick DeMan built a super GT4 Cayman, tested at the ROAR but did not run the race. GS BoP continues to evolve..might be worth have a chat with Rick if only to better inform you on the cars and options to consider As late as November last year, there were a few teams looking to put programs together for ST Caymans, you're probably best off contacting the current teams and jumping into their (established) programs.
Rebel Rock Racing aka Destiny Racing is running Caymans in the Continental Tire series. They will rent.
