The Porsche 718 Cayman GT4 RS is already an uncompromising driver's car with standard equipment – with the Manthey Kit it becomes a precision instrument. Its potential: 7:03.121 minutes for a lap on the 20.8-kilometre Nürburgring Nordschleife. In addition to the pure performance, which can be read from the lap time, the focus, as with all kits, is on driving ability. Predictable reactions and clear feedback from the vehicle are the factors that make the package attractive.
