Porsche is on a row, as it announces special editions of its 911 and 718 models. At this year’s Los Angeles Auto Show they, once again, introduced a track-only version of the Cayman, called the GT4 RS Clubsport. The mid-engine race car from Weisscach is based on the Porsche 718 GT4 RS, which also debuts on this year’s auto exhibition, in Los Angeles.


This is the third iteration of the Porsche 718 that is race-bred, following the 2019, 987-based Cayman GT4 Clubsport and the 2016 Cayman GT4 Clubsport before it. As before, the new Porsche 718 Cayman GT4 RS Clubsport is ready to hit the racetracks, from the factory.

The Engine

Being based on the also new Porsche 718 Cayman GT4 RS, the GT4 RS Clubsport is motivated by the same 4.0-liter, normally-aspirated flat-six engine that makes 493 horsepower and 343 pound-feet (465 Nm). While it matches the power output of the 991 GT3 RS and 991.2 GT3, the engine is actually that of a 911 GT3 CUP racecar. This is also a significant bump in power from the previous GT4 Clubsport, which had 425 horsepower and 313 pound-feet (425 Nm) from a 3.8-liter, normally-aspirated flat-six.

The GT4 RS Clubsport is 18 percent more powerful than the previous model. Its 4.0-liter flat-six also revs higher, making its peak power at 8,300 RPM - 800 RPM higher than the previous GT4 Clubsport. Peak torque is achieved at 6,000 RPM and the redline is 9,000 RPM.

The 2022 718 Cayman GT4 RS Clubsport also utilizes a seven-speed PDK gearbox, instead of the previous model’s six-speed PDK unit and features shorter gear ratios. Porsche claims that, depending on the track and series, the new GT4 RS Clubsport can achieve lap times, over two percent quicker than the previous Cayman GT4 Clubsport. The vehicle is also fully homologated and ready for use in SRO racing series, without any additional modifications.

Improved Drivability

Michael Dreiser – Manager of Sales and Distribution at Porsche Motorsport – said that the GT4 RS Clubsport has been developed, by combining the company’s previous racing experience with customers’ wishes. This was done in order to improve the car’s drivability and deliver a competitive product for future GT4 class competitions.

Numerous chassis improvements are also present on the GT4 RS Clubsport. Porsche’s latest GT4 features completely revised dampening technology, in order to maximize responsiveness and body control. The suspension features two-way adjustable shocks with three different spring rates available and sword-type anti-roll bars on both axles. The suspension setup allows for height, camber, and toe adjustments.

The Porsche GT4 RS Clubsport aerodynamics are designed to work with the enhanced chassis, for optimal control over the car. Specially-designed NACA ducts aid in cooling while the front dive planes and extended front spoiler increase front downforce, negating the risk of front-end lift.

One of the more distinctive exterior elements is the 911 GT3 R-inspired vents on the front wheel arches. The car also features air curtains that reduce turbulence around the front of the car and the underbody is fully enclosed. All this optimizes the airflow towards the rear diffuser. The tall rear wing features swan necks, just like on the latest Porsche 911 GT3 and has been given a 20mm long Gurney flap as well as two-stage adjustability.

Fully Equipped For Racing

Under the purposeful body, the GT4 RS Clubsport is just as race-focused. It features fore and aft-adjustable Recaro seats with six-point racing harnesses, compliant with the 2023 safety requirements, and a welded-in roll-cage. It also features safety nets, safety foam on the driver’s side, fire extinguishers, and a built-in air jack system.

At the back, there is an FT3 fuel-cell with a 115-liter (30.38 gallons) capacity. Two exhaust systems are available for the GT4 RS Clubsport, in order to be able to compete on racetracks with stricter noise limits. Porsche has made sure to prepare the new GT4 for the later addition of homologated headlights or openings for fast refueling, which would enable quick conversion to nighttime driving.

Competitive and Sustainable

The 2019 Porsche Cayman GT4 Clubsport, which was based on the 981 generation 718, was the first production car to feature body parts made of renewable natural-fiber composite materials. This is even truer for the GT4 RS Clubsport, as it features even more extensive use of such materials.

Parts such as the doors, wings, hood, ground effects at the front, and even the steering wheels are made of flax-based material. Porsche believes this is a viable alternative to carbon fiber and its use in motorsports will evaluate its applicability for road cars.

Porsche has revealed the new 718 Cayman GT4 RS Clubsport at the Los Angeles Auto Show. The mid-engined race car from Weissach is based on the new 718 Cayman GT4 RS road car which has also just been unveiled.

The most significant change is the 4.0 litre six-cylinder boxer engine. This high-revving powerplant has been taken directly from the 911 GT3 Cup race car and develops 500 PS in the 718 Cayman GT4 RS Clubsport – 75 PS more than the previous GT4 Clubsport model. In addition to many upgraded details, the focus in developing the new 718 Cayman GT4 RS Clubsport was on further improving overall performance. The standard 7-speed dual-clutch transmission (PDK) fitted to the car now uses all seven forward gears, rather than six. All gears feature shorter ratios than in the previous model. Depending on the track and series-specific regulations, the new 718 Cayman GT4 RS Clubsport can achieve lap times that are over two percent quicker than the previous model. The homologated vehicle is track-ready ex factory and can be used in SRO racing series around the world without further modifications.

Faster lap times and further improvement in driveability
We have incorporated our experience of the last three years of running the previous GT4 Clubsport as well as customer wishes into the development of the new car,“ said Michael Dreiser, Manager of Sales and Distribution at Porsche Motorsport. “Faster lap times combined with a further improvement in driveability offer our customers a competitive product for the upcoming racing seasons in GT4 class racing competitions around the world.“ Porsche began offering the Cayman GT4 Clubsport of the 981 generation in 2016, entering into this new customer racing format early with a competitive car. A total of 421 units were built prior to 2018. The next generation model, which was based on the 718 Cayman GT4, debuted in 2019. It was also an extremely success car, with around 500 units produced to date. One of the reasons for the strong demand for these vehicles is due to the low running costs. The use of well-proven series production technology combined with racing-specific components significantly reduces the costs for customer teams.

The 718 Cayman GT4 RS Clubsport continues this tradition and offers a further improvement in terms of its competitiveness. The 500 PS 4.0 litre six-cylinder boxer engine taken directly from the current 911 GT3 Cup racing car is almost 18 per cent more powerful than the 3.8 litre engine that was used in the previous model. Thanks to an optimised air intake, maximum power is achieved at 8,300 rpm – 800 rpm higher than the previous engine. The new engine revs up to 9,000 rpm. It develops 465 newton metres (Nm) at 6,000 rpm instead of the previous 425 Nm at 6,600 rpm. The result is a much wider usable speed band, which makes driving the car much easier for pro-racers and amateur drivers alike.

Modifications to the chassis have also improved the handling of the 718 Cayman GT4 RS Clubsport. The damper technology has been revised from the ground up in order to achieve an optimised vehicle responsiveness and a further improvement in body control. This has had a significant impact on the overall performance of the vehicle and handling. Upgrades include the use of two-way adjustable shock absorbers with improved characteristics, in addition to adjustable sword-type anti-roll bars front and rear.

Vehicle height, camber and toe are also adjustable. Furthermore, three different spring rates for front and rear axle are now available. Special NACA ducts in the bonnet are designed to direct the air flow more efficiently to the large racing braking system fitted with 380 millimetre steel brake discs. The Porsche Stability Management System (PSM) is designed specifically for motorsports and includes a switch for traction control (TC), ABS and an updated stability control system.

Excellent aerodynamics ensure precise handling
Excellent aerodynamics ensure that the precise and controllable handling of the 718 Cayman GT4 RS Clubsport remains well-balanced even in fast curves. Front dive planes and an extended front spoiler lip increase downforce at the front axle. Wheel arch vents in the wings inspired by the 911 GT3 R and air curtains specifically designed to calm the air turbulence around the front wheels, while the fully enclosed underbody optimises air flow to the diffusor at the rear of the car. The swan neck rear wing has now been given a 20 millimetre long Gurney flap and an adjustment range extended by two additional stages.

The previous 718 Cayman GT4 Clubsport was the first ever series production race car to use body parts made of renewable natural-fibre composite material. In the case of the new GT4 RS Clubsport, even more extensive use of this material is made in the vehicle as a whole. In addition to the doors and the rear wing, the bonnet, the wings, the aerodynamic components at the front end and the steering wheel are now made of this material. The use of this flax-based fibre as an alternative to carbon fibre composite material can now be tested in motorsports for its use in road cars. Porsche has been using motorsports as a test bed for technology, processes and materials potentially capable of being used in road cars for over 70 years now.

Der 718 Cayman GT4 RS Clubsport is ready for racing
The 718 Cayman GT4 RS Clubsport is equipped to meet all the prerequisites allowing it to compete in racing events directly from the factory. This begins with the welded-in roll cage and the fore and aft adjustable Recaro racing seat, and extends from 2023 compliant six-point racing safety harnesses and safety nets to the fire extinguisher system and the built-in air jack system with three jacks. The new safety foam on the driver’s side meets the international requirements of the SRO racing series.

The FT3 safety fuel cell can take up to 115 litres of fuel, making it suitable for endurance racing. Additionally, Porsche offers two different exhaust systems, allowing the GT4 RS Clubsport to compete at tracks with stricter noise limits. The vehicle is also prepared for the later addition of homologated headlights or openings in the bonnet for fast refueling to enable the car to be converted quickly for nighttime endurance racing.
