What is the difference between Porsche 911 GT3RS and GT2RS?

What is the difference between Porsche 911 GT3RS and GT2RS?


The Porsche 993 GT2 was initially built to meet racing approval standards and the Porsche GT3 RS is featured “zero lift” aerodynamics, meaning the car creates only aerodynamic downforce and no grip-diminishing “lift” upwards and away from the road.

As cited from Samantha Baker from Porsche Centre North Toronto they state the difference between the Porsche GT2 RS and GT3RS. In 2016 the 991.GT3 RS was released. The that GT2 RS and GT3 RS were released months apart from each other. The new models are upgraded with new suspension that have metal ball joints instead of rubber, which offers better stability, precision and handling. The spring rates have also been increased to improve handling.


The differences is that the Porsche GT3RS is that it is built off the naturally aspirated 4.0 liter flat-six engine and the GT2 RS is built off of the 3.8 liter flat six twin turbo engine of the 911 turbo S. The Porsche GT2 RS has larger turbochargers, modified crankcase, different pistons, a new multi-tube air filter, enlarged airducts, larger intercoolers, and a unique water injection system and this water system uses distilled water that is stored in a water tank in the front of the vehicle.  The GT2 RS is about 300lbs lighter than the Porsche Turbo S since it is not all wheel drive. Also a shorter rear axle ratio than the turbo S and more carbon fibre.

The GT2 RS and GT3 RS have different facias due to the different cooling requirements and exhaust system.  The GT2 RS comes standard with the carbon ceramic brakes with the gray cast iron rotors.

Available as an option, the GT3 RS can upgrade to PCCB’s. (PORSCHE Ceramic Composite Brake.


These excellent cars may drive differently for each individual driver but Porsche has something available for that driving enthusiast.
