ATLANTA — Porsche has announced a Manthey Kit for the 718 Cayman GT4 RS that is specially optimized for use on racetracks.
The 493 hp GT4 RS with the Manthey Kit completed a lap at the Nürburgring Nordschleife in 7:03.121 minutes. This makes it over six seconds quicker than the 718 Cayman GT4 RS without the upgrade kit.
The modifications focus on aerodynamics and chassis components. Brake pads designed for the track are available as an option.
The new kit was developed especially for track days and in close collaboration between engineers at Porsche Motorsport and the Nordschleife specialists at Manthey.
Adjustable coil-over suspension with modified spring rates
Together with Manthey, Porsche has developed a special coil-over suspension with an inverted set-up for the 718 Cayman GT4 RS that can be adapted for the track. The spring struts can be adjusted to four different positions, and the rebound and compression stages can also be adjusted without the need for tools.
The spring rates on the front suspension have been increased by 20 percent. The chassis is available in two versions – for cars with and without a front axle lift system on the front axle.
Steel brake lines are also a standard component of the kit. This guarantees an exact pressure point, ensuring optimal braking power delivery. Special racing brake pads with particularly constant friction behavior over a wide temperature range are optionally available. I
Illuminated door sill guards with the Manthey logo are available to personalize the car visually. Towing loops are also optionally available, designed especially for the track.
More than six seconds faster on the Nordschleife
The 718 Cayman GT4 RS with the Manthey Kit is able to demonstrate its full potential on the Nürburgring Nordschleife, the traditional benchmark for sports cars at Porsche. With Porsche brand ambassador Jörg Bergmeister at the wheel, the modified GT sports car completed the 12.9 miles course in the Eifel at 18 degrees Celsius under an overcast sky in 7:03.121 minutes – over six seconds faster than the series-production 718 Cayman GT4 RS did the previous year. Both cars were equipped with the optional Michelin Pilot Sport Cup 2 R tires. The lap time was certified by a notary on site.
The kit is intended to be distributed in the U.S. market. Timing of its availability and pricing will be announced at a later date. The manufacturer’s warranty for the 718 Cayman GT4 RS is unaffected.
