Porsche turns the 718 Cayman GT4 RS into a tougher circuit tool with a Manthey package for drivers balancing road use and track days. Priced at about $60,000, the upgrade reworks the car's chassis and aerodynamics while keeping the coupe street legal and the engine untouched.
Manthey brings Nürburgring race knowledge into Porsche's road-car lineup, where the goal is lap-time composure rather than a power gain. By concentrating on grip and stability, the kit aims to make the GT4 RS steadier through long, technical sections.
At about $60,000, the package opens a factory-backed upsell for GT4 RS owners who want a sharper track car without moving to a race build. Keeping the car road legal also widens the buyer pool beyond dedicated competition use and supports drive-to-track use between events.
