Tastiest Porsche Cayman ever? Has to be this one. It’s the 718 Cayman in already pretty darned tasty GT4 form but with two little but important initials at the end: RS. And as you expect of Porsche’s RS breed, this is far more than just a once-over-lightly. Plenty of 911s wouldn’t see which way this baby went around the Nürburgring.
