The Manthey Kit is specially optimised for use on track.
7 minutes 3.121 seconds or 6.179 seconds quicker than the regular 718 Cayman GT4 RS around the Nürburgring Nordschleife. That’s what the Manthey Kit brings to the table, and will be available from Porsche Centres worldwide.
First up are the addition of functional aero parts. In front, flaps and new air curtains with a wheel arch Gurney flap, and a new carbon underbody with diffusers increase downforce on the front end.
At the back, there is an 85mm wider rear wing that features a new wing blade and larger endplates, which work together to increase rear downforce. This new wing assembly is four-stage adjustable to tailor aero to different driving situations. To withstand this increased downforce in the rear, the bodywork of the rear engine cover is reinforced with a carbon-weave finish. At 200km/h, with the rear wing set to Performance, total downforce increases from 89kg to 169kg.
Adding to the aero effects are the CFRP aero-discs on the rear wheels, which help to smooth airflow and cut down on turbulence.
Next up is suspension. Together with Manthey, Porsche has developed a special coilover suspension with an inverted set-up that can be adapted for the track. The spring struts can be adjusted to four different positions, and tool-less adjustments are available for rebound and compression. Spring rates in front have gone up 20 per cent. Not to worry if your GT4 RS has a front-axle lift system, for there is a version of the coil-overs for this as well.
Stainless steel braided brake lines are also a part of the Manthey Kit to offer much more precise and even braking. Need more hardcore in your GT4 RS? Specify the optional racing brake pads, which offer a particularly constant friction coefficient over a wider temperature range, and enjoy more consistent braking on track.
Other optional upgrades are also available to suit one’s palette. Illuminated door sill guards with the Manthey logo can be specified to personalise the car visually. Towing loops are also optionally available, designed especially for the track. A specially designed CFRP rear spoiler attachment, which is finished with carbon weave, is attached to the standard rear spoiler, and further increases downforce on the rear axle by around four per cent in combination with the bigger rear wing. Optional louvres or wheel arch vents finished in carbon weave in the front wings are also available to match the look of the Weissach package.
The Manthey Kit will be sold by Porsche Centres worldwide, and its launch in Europe is expected to be in December 2023 with other markets following thereafter. Country-specific pricing will be listed in the accessory finder. Ready to kit out your 718 Cayman GT4 RS for even more hardcore track days?
