Test Porsche 718 Cayman GT4 RS: an investment that entertains and makes money

Have you ever thought about buying a car ready for the tracks that can earn you some money? It’s this one…

It is common to worry about the devaluation of a car at the time of purchase. After all, no one wants to lose a lot of money when reselling and they even prioritize this analysis in the decision. Lately, having a Porsche in the garage has been a good way to earn money, especially those rarer and more limited versions globally, such as the 718 Cayman GT4 RS. 

On the other hand, it is the most extreme Porsche 718 Cayman in the catalogue. From a sociable sports car, it became a racing car with license plates, complete with semi-slick tires, carbon fiber, crafted aerodynamics and fixed shell seats. Before turning money, it is possible to have fun and enjoy it until you find your limit with a pilot, since the car will be much more difficult to find. 

In 2021, I took the 718 Cayman GT4 and 911 GT3 to the track myself in a Motor1.com special. Obviously the 911 992 is something that goes beyond expectations in this track ready version , but the GT4 didn’t do badly and showed that, despite being a gateway in this lineage, it was very good. Except that the GT4 RS is absurd and would, in a good way, replace a 911 GT3 in my garage – at least until I get my hands on the GT3 RS…

That GT4 already brought many differences to a normal Cayman. For the RS, engineering focused on more power, less weight, improved aerodynamics and even sharper handling. And to think that GT4 had already impressed me so much and the RS brought even more experiences and the desire to get rich enough to have almost R$ 3 million in the account – yeah, I’ll explain that in a moment. 

The first point is that that GT4 already had a 6-cylinder boxer engine, 4.0 aspirated, with 420 hp (at 7,600 rpm) and 42.8 kgfm at 5,500 rpm, with a limiter at 8,000 rpm. For the RS, they took the engine from the 911 GT3, which also has a dry sump (a system that pumps lubricant into the engine instead of keeping it in the engine, more efficient on the tracks) and individual intake butterflies, which here it has 500 hp (8,400 rpm) and 45.9 kgfm (6,750 rpm) hitting 9,000 rpm. It just doesn’t have the 911 numbers because of the tighter vault and different exhaust system. On the other hand, it is lighter, with 1,415 kg, against 1,450 kg of the 992. 

Engine in place, let’s take care of how this car handles. The suspension receives components focused on the tracks, such as ball joints, which are more precise and less variable than traditional rubber ones. Springs, bars and dampers are from the GT4 RS, which doesn’t care if you’re going to use the car on the street. Shock absorbers are adaptive, but vary between hard, very hard and very hard. As an option, the front suspension has a small air bag to lift a few centimeters and facilitate entering and exiting ramps, for example. Something useful from $19,840. At the rear, you can adjust the camber and stiffness of the bars, for example.
