The 718 Cayman GT4 RS represents the pinnacle of Porsche's mid-engine sports car development. For the first time, Porsche's GT division dropped the 4.0L, 9,000 RPM flat-six from the 992 GT3 into the Cayman's chassis. The result is 493 hp in a lighter, more agile package, complete with aggressive aerodynamics, carbon fiber panels, and dramatic air intakes that replace the rear quarter windows, creating an unforgettable induction sound inside the cabin.
Collectors immediately recognized the GT4 RS as a special model, and it's widely considered a future classic. It's the most extreme, track-focused version of the Cayman ever produced and likely the last to feature a naturally aspirated engine of this caliber. The driving experience is more raw and visceral than its 911 GT3 sibling, offering a unique blend of mid-engine balance and motorsport-derived performance that appeals to purists.
Since its launch, demand has consistently outpaced supply, causing market prices to remain significantly above its original MSRP. While the initial frenzy has cooled, well-optioned cars, especially those with the Weissach Package, continue to command strong premiums. The market's high-water mark of $1.8 million was for a unique 'Tribute to 718 RS 60 Spyder' sold at a 2023 charity auction, while most examples trade in a more predictable range.
Buying Tips
- Prioritize cars with the optional Weissach Package. It adds a carbon fiber hood, roof, rear wing, and other components that are highly desirable and crucial for resale value.
- The front axle lift system is a must-have option for road use. The car's low front splitter is vulnerable to damage on driveways and speed bumps, making this a critical quality-of-life feature.
- Get a DME (Digital Motor Electronics) report to check for engine over-revs. This is standard practice for any Porsche GT car and will reveal if the engine has been subjected to mechanical stress.
- Carefully inspect consumables. Check the condition of the Michelin Pilot Sport Cup 2 tires and the PCCB carbon-ceramic brakes, if equipped. Replacing either is very expensive and can indicate hard track use.
- Paint to Sample (PTS) colors and magnesium wheels add a significant premium. Review the full Monroney sticker or build sheet to understand every option on a prospective car.
Prices range from $155,000 to $1,800,000, though the highest sales are typically for unique charity auction vehicles.
