Porsche 718 Cayman GT4 and GT4 RS Buyers Guide

When the Porsche 718 Cayman GT4 was introduced in 2019, it brought an exciting moment for Porsche enthusiasts, bringing naturally aspirated power back to the mid-engine lineup. Designed to deliver performance on both the road and track, the GT4 revived the raw driving dynamics that purists crave.

Three years later, in 2022, Porsche unveiled the 718 Cayman GT4 RS, taking the platform to new heights with the race-focused philosophy that defines every RS model in Porsche’s lineup.

At the heart of the 718 Cayman GT4 lies a 4.0-liter naturally aspirated flat-six engine, delivering 414 hp and 309 lb-ft of torque. This engine offers a high-revving character, with a redline of 8,000 rpm, paired with either a 6-speed manual transmission for purists or an optional 7-speed PDK dual-clutch transmission for faster, more precise shifts.

The GT4 RS raises the bar even higher, borrowing the 4.0-liter flat-six from the 992-generation 911 GT3, producing an impressive 493 hp and 331 lb-ft of torque, exclusively paired with the PDK transmission. This ensures lightning-fast acceleration, with the GT4 RS sprinting from 0 to 60 mph in just 3.2 seconds.

The exterior design of the 718 Cayman GT4 and GT4 RS is both aggressive and functional. The GT4 features a fixed rear wing, large front air intakes, and an aerodynamic splitter, all optimized to generate significant downforce while maintaining it’s timeless styling.

The GT4 RS takes aerodynamics to a new level, with a swan-neck rear wing, enlarged front diffuser, and a lightweight carbon-fiber hood. Lightweight materials such as aluminum and carbon fiber are used extensively in both variants. Inside, the cabin is tailored for a driver-focused experience. Both models feature sport bucket seats, Alcantara upholstery.

The GT4 RS further emphasizes weight savings, offering carbon-fiber-reinforced plastic (CFRP) seats, reduced sound insulation, and door pull straps in place of traditional handles. Advanced technology like Porsche Communication Management (PCM) with Apple CarPlay ensures a modern touch within a purpose-built cockpit.

The 718 Cayman GT4 and GT4 RS sit in a highly competitive segment, facing rivals like the Chevrolet Corvette Z06, Lotus Emira, and Jaguar F-SVR Coupe.

Despite the competition, the GT4 and GT4 RS are in a league of their own with their naturally aspirated engines, mid-engine balance, and Porsche’s unmatched motorsport heritage, making them favorites among enthusiasts seeking the best driving experience.

Porsche 718 GT4 and GT4 RS Common Problems

While the Porsche 718 Cayman GT4 and GT4 RS a true performance sports cars, no car is entirely free of potential issues. Owners have reported a few recurring problems that, while not universal, are worth noting for prospective buyers. These concerns primarily revolve around mechanical reliability, manufacturing defects, and usability quirks, particularly under high-performance conditions. Below is a detailed look at some of the most commonly reported issues with these cars.

Keep in mind, that it is essential 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.

Engine Reliability Concerns: Some 718 GT4 RS owners have reported significant engine issues, including complete engine failures. These failures often required full engine replacements, even on relatively low-mileage cars. While not widespread, these problems have raised concerns about long-term reliability under extended track use or high-performance driving conditions.

Connecting Rod Defects: A number of 2021 GT4 models were delayed or recalled due to defective connecting rods, which are critical for the engine’s function. These defects were identified during quality control and led to engine replacements prior to delivery. Porsche addressed this issue, but affected cars caused frustration for early adopters.

Wheel Detachment Risk: Porsche issued a recall for certain 718 models, including the GT4 and GT4 RS, due to issues with defective central locking wheel nuts. If not replaced, these nuts could fail, resulting in wheels potentially detaching while driving. This issue posed serious safety risks, particularly at high speeds or during track use, where wheel stresses are greater.

Lifter Noise in GTS 4.0 Engines: Some owners of the 4.0-liter flat-six engine, especially in the GTS 4.0 variant, reported lifter noise, which could indicate wear or improper lubrication. While the noise does not always signify a critical problem, it has raised concerns about long-term engine durability, especially for those using the car extensively on track days.

Fueling Difficulties: Certain 718 models, including the GT4, have exhibited a problem where the fuel nozzle prematurely shuts off during refueling. This issue makes it difficult to fill the tank and can be particularly inconvenient on longer trips or at the track. Owners have reported inconsistent fixes for this problem, ranging from software updates to replacing fuel system components.

Maintenance and Ownership Costs

Compared to other high-performance sports cars, owning a Porsche 718 Cayman GT4 or GT4 RS is generally considered to come with relatively manageable maintenance requirements.

However, it’s important to keep in mind that regular maintenance and occasional repairs are essential to ensure optimal performance, especially if the car is frequently used for track driving. Maintenance costs can vary significantly depending on whether you choose to service the car at an authorized Porsche dealership or through a trusted independent mechanic.

Below are the recommended service schedules and intervals provided by Porsche:

Annual Maintenance (Every 10,000 miles or 1 year):

• Oil and Filter Change

• Vehicle Inspection

• Tire Inspection and Rotation

Every 20,000 miles or 2 years:

Here is a rough estimate of typical service costs associated with the Porsche 718 Cayman GT4 or GT4 RS:

• Oil Change – Oil changes are essential to keep the 4.0-liter flat-six engine running smoothly, especially under the demands of spirited driving or track use. At a Porsche dealership, an oil change typically costs between $300 and $500, reflecting the use of Porsche-approved synthetic oil and OEM filters. Independent shops can often perform the same service for $200 to $350, depending on labor rates and parts pricing.

• Minor Service – A minor service includes an oil change, fluid top-offs, brake system inspection, and a multi-point vehicle check to ensure all systems are functioning properly. At a dealership, this service usually costs around $500 to $700, while independent shops may offer it for $400 to $600, providing similar thoroughness at a slightly reduced price.

• Major Service – Major services are more comprehensive, covering all aspects of a minor service while also including spark plug replacements, air and cabin filter changes, brake fluid replacement, and detailed inspections. At a dealership, a major service typically ranges from $1,200 to $1,500, reflecting the labor-intensive nature of the service and the use of genuine Porsche parts. Independent shops can often complete the same service for $900 to $1,200, offering a cost-effective alternative without compromising quality.

• Tires – High-performance tires like the Michelin Pilot Sport Cup 2 are a crucial part of the 718 GT4 and GT4 RS experience, providing exceptional grip and handling. However, these tires wear faster due to the car’s aggressive driving dynamics. Replacing a set of four performance tires at a Porsche dealership generally costs between $1,800 and $2,500, including mounting and balancing. Independent shops may charge slightly less, with prices ranging from $1,500 to $2,200, depending on the tire brand and specifications.

• Brakes – The high-performance braking systems in these models, particularly when subjected to frequent track use, require regular maintenance. Replacing the brake pads and rotors on all four wheels costs approximately $2,000 to $2,500 at a dealership, while independent shops typically charge between $1,500 and $2,000. Owners also have the option to choose high-quality aftermarket components for additional cost savings.

• Clutch – For manual transmission models, clutch replacement is a labor-intensive service costing $2,500 to $3,500 at a dealership and $2,000 to $3,000 at independent shops. For PDK-equipped models, while clutch replacement isn’t needed, the PDK transmission fluid requires periodic replacement, costing around $800 to $1,200 at dealerships and $600 to $1,000 at independent shops. Regular maintenance ensures smooth operation, especially for track use.
