- Porsche has revealed the new Manthey Kit for the 718 Cayman GT4 RS.
- A Manthey Kit equipped GT4 RS recorded a time of 7:03.121 at the Nordschleife, a 6.179 second improvement over the stock car.
- Porsche hasn’t announced pricing or when the kit will be available, but it promises to sell the kit to the U.S. market.
Improvements at the race track are often measured in decimals. Shaving a tenth of second off here, or a few thousands off there can add up over time. The Manthey Kit Porsche just announced for the 718 GT4 RS spits in the face of those decimals and takes full seconds away from the stock car’s Nürburgring Nordschleife time, 6.179 seconds to be exact.
The new kit adds flaps and air curtains along with a wheel arch Gurney flap at the front. A new carbon underbody complete with diffusers help improve downforce at the front of the car. The rear wing at the back of the car is 3.4 inches wider than the standard version, and features larger side blades to increased downforce at the back of the car. It also adds a fourth position for more variability. With the rear wing set to the performance position intended for the track, downforce is nearly doubled at 124 mph, from 196 to 372 pounds. The increase in downforce is enough to warrant a carbon weave for reinforcement over the engine cover.
Extra Adjustment
Porsche and Manthey jointly developed a new coil-over suspension for the car, with spring struts that can be adjusted to four positions and rebound and compression stages that can be adjusted without the need for tools. Spring rates on the front suspension have been increased by 20 percent. The Manthey kit also adds braided steel brake lines, with the option to add racing brake pads as well.
According to Porsche, the kit will be distributed to the U.S. market, though timing of the availability and pricing haven’t been released yet. Importantly, the manufacturer’s warranty for the car isn’t affected by the addition of the kit.

After a brief stint as a detailer for a local dealership group in college, he knew he needed a more permanent way to drive all the new cars he couldn’t afford and decided to pursue a career in auto writing. By hounding his college professors at the University of Wisconsin-Milwaukee, he was able to travel Wisconsin seeking out stories in the auto world before landing his dream job at Car and Driver. His new goal is to delay the inevitable demise of his 2010 Volkswagen Golf.
