The "speed shape model" for my 2020 C8 arrived almost 2 years after I took delivery, but that's one of the longer times I've heard about. By then, the "coupon" that came with the speed shape model for the Ron Fellows Performance Driving School, had long expired. GM subsidizes the 2-day Corvette Owner's School: the original owner of a new Corvette pays US$1,000 rather than the regular price of around US$3,700, so it's a fabulous deal, you learn a ton about your C8 and driving safety in general, and it's lots of fun (EVERYONE who's gone, recommends it). All new Corvette owners who want to attend the school, can register with their VIN and you're supposed to attend within the first year of ownership. The coupon isn't needed at all. GM doesn't send the speed shape models; they're sent by a marketing company hired by GM. They've sent out speed shape models for every C8 year and we've had members of these Forums who've gotten their speed shape models for the 2023 Z06 already. It's slightly different than the speed shape models for the C8 Stingray, but the same idea.
