The 911 GT3 R Rennsport wasn't the only world premiere Porsche had over the weekend at the Weathertech Raceway Laguna Seca in California. Attending the same Rennsport Reunion 7 event was a special 718 Cayman GT4 RS of which only two are ever going to be made. The track-focused road car was created in collaboration with TAG Heuer to celebrate the 550 Coupe that raced in the 1953 Carrera Panamericana.
