The introduction of the Porsche 991.1 GT3 RS took the supercar world by storm. It replaced the 997.2 GT3 RS on an entirely new 991 chassis. It is regarded as one of the most hardcore street legal production cars around with Porsche's trusted reliability.
Each time a new GT3 RS is released, it sets the bar high for the successor to follow.
Slotting in as the big brother to the lesser expensive GT3, the GT3 RS is a car meant for drivers that are serious about lap times.
It features a 4.0 liter engine that pushes out 500 hp, versus 3.8 liters and 475 hp in the GT3. The RS engine revs up fast, helped by light titanium rods. Its middle titanium exhaust makes a very loud sound near the high 8800-rpm redline.
The GT3 RS has moved away from the manual transmission option, and now exclusively comes equipped with Porsche's exceptional PDK dual-clutch transmission, which is renowned for its seamless gear shifting and performance capabilities.
When you see a GT3 RS, you will not mistake it for a standard GT3. Immediately, you will notice the wider track, large rear wing, and more aggressive bodywork. Carrying on the tradition of high-performance GT3 RS models that began with the 996 generations in 2003 (not available in the U.S.), this newest iteration, like its predecessors, enhances track performance through increased tire grip and extensive aerodynamic improvements.
It comes with a wider body than the 911 Turbo models, making it 1.1 inches wider than the GT3. Porsche also changed the GT3 RS to use the rear fender ducts for air intake, which are used for intercoolers in the Turbo version.
The RS includes a magnesium roof and carbon-fiber front fenders, trunk lid, and rear engine cover. The front splitter, the ducktail-like engine cover, and the huge adjustable rear wing over five feet high are all part of the improved aerodynamics. These changes create three times more downforce than the GT3.
Inside the GT3 RS interior, you will find that it has the same dashboard as all other 991.1 911s, but a key difference is the Alcantara steering wheel and the carbon fiber racing seats that were also in the Porsche 918 hypercar. Although some came with comfort seats, the racing seats were the one that was most desirable.
The 991.1 GT3 RS's driving dynamics were a much more drastic improvement over the 997.2 GT3 RS it replaced.
Driving the GT3 RS on public roads can be a bit disappointing, as you won't be able to truly experience its full capabilities. This makes you more eager to take it to a racetrack and uncover its true potential. However, the GT3 RS surprisingly doesn't demand many compromises compared to the standard GT3. Although it might be slightly noisier and wider, the car still offers a comfortable ride, and the PDK gearbox performs seamlessly.
It features a more advanced and sophisticated drivetrain, which results in a smoother and more controlled driving experience.
Some of the competitors to the GT3 RS were the Ferrari 488 GTB, Lamborghini Huracan, and the McLaren 570S. The Porsche is the only one that is the most track-focused and hard-core that most resembles a street-legal race car out of the competition.
Overall, the GT3 RS is an incredible performance car, and those that buy one are most likely track enthusiasts you will not regret buying one.
Model Changes (Breakdown by Year)
2015 Porsche GT3 RS
The 2015 model was the first year of the 991.1 GT3 RS, which replaced the 997.2 GT3 RS.
Featuring a 4.0-litre engine that produces 500 hp and 340 lb-ft of torque.
As usual for Porsche, the design is based on function, and this feature helps push the front wheels down for better grip. A standout feature is the special air vents in the front wheel arches that reach the top part of the sides, just like a real race car.
The starting base price was around $176,000 slotting it right with the Ferrari 488 GTB, Lamborghini Huracan, and the McLaren 570s.
2016 Porsche GT3 RS
For the 2016 GT3 RS, everything remained the same with no changes.
2017 Porsche GT3 RS
No GT3 RS was produced for the year 2017.
That is because the 991.1 GT3 RS was in anticipation of the mid-life cycle update that came in 2018.
2018 Porsche GT3 RS
In 2018, the Porsche 991.2 GT3 RS was launched as an updated version. In short, an already great car became even better.
This is the best 911 without turbochargers. Almost all 911 models use turbocharging for more power and less CO2, but the GT3 and GT3 RS stay naturally aspirated. This gives more accurate power, higher RPMs, and an exciting sound.
It now comes with 513 hp (38 hp more than the 991.1 GT3 RS) and 347 lb-ft of torque, providing increased performance and quicker acceleration for an even more exciting driving experience.
The most noticeable difference is the body, which is wider, has more openings and has larger spoilers. It shares its body with the 911 Turbo, which is why it has cooling vents in the rear arches. These vents were designed for the Turbo's intercoolers, but in the GT3 RS, they supply air to the big airbox at the back.
The air ducts inside the car make the intake sound really amazing. The front part is wider than the Turbo, and it looks like a race car with its tilted position, thanks to the new 21-inch rear wheels and 20-inch front wheels.
The suspension is more advanced than the standard GT3, the aero kit produces increased downforce, and the 4.0-liter flat-six engine provides additional power and torque. This engine is closely connected to the one used in the 911 GT3 Cup race car.
Base price started at $188,000 ($12,000 more than the pre-facelift GT3 RS).
Porsche 991 GT3 RS Common Problems
The Porsche 991 GT3 RS is regarded as a supercar that is not only reliable but also one of the more hardcore track and street machines on the market.
Many people have driven their Porsche GT3 RS for extended distances, some even exceeding 80,000 miles, proving its reliability.
This breaks the traditional belief that supercars are inherently unreliable.
However, it is essential to keep in mind that all cars, even supercars, can have issues and it is crucial to perform a Pre-Purchase Inspection (PPI) from an authorized dealer or experienced independent mechanic to reveal all issues.
Fingerprint bearing failure: Earlier models of the 991 GT3 RS experienced engine failures due to faulty connecting rod bearings. Porsche addressed this issue by replacing the affected engines and updating the bearings in newer models.
Intermediate Shaft (IMS) bearing failure: Although more prevalent in earlier generations of the Porsche 911, some GT3 RS models have experienced IMS bearing failure, which could lead to catastrophic engine damage. Porsche has made significant improvements in recent years to address this issue.
Coolant leaks: Some GT3 RS engines have been reported to suffer from coolant leaks, mainly due to cracked coolant lines or faulty connections. Regular inspection and maintenance can help prevent this issue.
Overheating issues: There have been reports that the GT3 RS can sometimes face overheating problems, especially during extended periods of hard driving or in hot climates. Ensuring proper cooling system maintenance and using high-quality engine oil can help mitigate this issue.

Options List
Porsche is well-known for offering an extensive selection of customization options to choose from. Here, we'll highlight some of the most sought-after choices among GT3 RS owners.
A popular option was the Sport Chrono Package which includes built-in timers and the Porsche Track Precision app for smartphones. This app uses GPS to measure lap times and records various driving data like speed, side-to-side movement, and acceleration or deceleration.
It organizes this information, allowing drivers to share and compare their data with others.
The Porsche Ceramic Composite Brake (PCCB) is a favored choice, particularly for those who enjoy taking their cars to the track. These ceramic brakes are distinguishable by their yellow calipers, as opposed to the red calipers found on steel brakes. This feature is quite useful for GT3 RS owners who enjoy taking their cars to the racetrack.
