Porsche recently unveiled an impressive performance upgrade for the 368 kW 718 Cayman GT4 RS. The thing is, the new and optional Manthey-Racing Kit only pays attention to the handling dynamics and no modifications are done to the power output. Behind the wheel during this amazing lap of the Nordschleife circuit was Porsche brand ambassador Jörg Bergmeister, who completed a lap in a jaw-dropping 7:03.121 minutes. The 718 Cayman GT4 RS with the Manthey Kit demonstrated its dominance by outpacing its counterpart without the upgrade by an exact margin of 6.179 seconds. That’s a huge gap for an upgrade focused on enhancing aerodynamics and chassis components, of which the modifications were the result of a collab between engineers from Porsche Motorsport and Nordschleife specialists at Manthey and were developed exclusively for track day enthusiasts. Visually recognizable by its aero parts, the Manthey Kit showcases a range of enhancements - at the front, flaps and new air curtains complement a wheel arch Gurney flap and a carbon underbody with diffusers to maximize front-end downforce, while the rear of the car has an 85-millimetre wider wing with a new blade and larger endplates, increasing rear downforce. With improved aero, there was a need to reinforce the rear engine cover's bodywork with a carbon-weave finish. The aerodiscs on the rear wheels, made of CFRP, help reduce turbulence and complete the aerodynamic package. When the rear wing is set to Performance mode for track use, at 200 km/h the total downforce rises from 89 kg to a massive 169 kg.
Take a look at the YouTube video that shows the Manthey-Racing upgraded Porsche 718 Cayman GT4 RS tackling the famed Nürburgring Nordschleife circuit in Germany at the hands of Porsche ambassador Jörg Bergmeister. As you'll see, he managed to shave more than 6 seconds off the time set by the production version of the car, proof that the Manthey Kit is worth the money: On board footage of the Manthey Racing Porsche 718 Cayman GT4 RS is exceptional | CWMedia
