The indirect predecessor of the first 911 GT2 (type 993 ) was the Porsche 911 Turbo S Le Mans GT (Type 964 ). Like the GT2 was the Turbo S LM - GT, a racing version of the turbo that offered by Amenities waiver and weight optimization and a revised suspension and an uprated engine better performance by a lower power to weight ratio.
The term GT2 has only historically to do with the eponymous motor racing regulations.
