The Porsche 718 Cayman GT4 RS is already a pint-sized supercar-slayer. Now an optional Manthey Kit, with enhanced aero and better brakes, stretches its possible amassed additional.
The upgraded GT4 RS is a joint effort between the ‘Nordschleife consultants’ at Manthey and Porsche Motorsport. By no technique heard of Manthey? The revered German racing group has seven Nürburgring 24 Hours victories to its title, and has been majority-owned by Porsche AG since 2013.
Because the tip rung on the 718 Cayman ladder, the GT4 RS begins from £123,000, though a prolonged waiting list technique we’ve seen ‘flipped’ autos advertised for twice that amount. The price for the Manthey Kit is amassed to be confirmed, nevertheless this is able to per chance be offered by UK Porsche dealers from December.
The first factor to video display is that the Manthey Kit doesn’t contain any extra strength. The 4.0-litre naturally aspirated flat-six engine – shared with the 911 GT3 – amassed develops 500hp at a heady 8,400rpm: pretty for 0-62mph in 3.4 seconds and a top depart of 194mph.
As an change, the enhancements are primarily pondering about aerodynamics. The entrance of the automobile contains new air curtains, wheelarch Gurney flaps and a carbon fibre undertray with built-in diffusers. On the rear, CFRP aerodisc wheels lend a hand decrease turbulence, while an 85mm wider spoiler offers four phases of adjustment, virtually doubling downforce to 169kg at 200kph (124mph) in its Performance setting.
Extra adjustments by Manthey (affirm it: ‘Man-tie’) contain 20 p.c stiffer springs for the coilover suspension and optional racing brake pads. You may possibly presumably additionally additionally specify entrance and rear towing loops, in case it all ends within the fracture barrier, along with some – fairly much less purposeful – illuminated door sill guards with the Manthey mark.

Inevitably, all this fair-tuning and obsessive attention to component ends in a Nürburgring lap-time. Driven by Jörg Bergmeister, and carrying large-sticky (nevertheless avenue-legal) Michelin Pilot Sport Cup 2 R tyres, the Manthey GT4 RS lapped the ‘Green Hell’ in 7min 3.12sec. That’s 6.18 seconds sooner than the identical outdated car, albeit amassed within the abet of essentially the latest Porsche 911 GT3 RS (6min 49.33sec).
How fundamental difference the Manthey Kit makes within the staunch world, even for these tackling the occasional display screen day, is open to inquire, nevertheless there’s an obvious charm to owning the ultimate GT4 RS – and indeed the quickest, most low Cayman earlier than its electrical successor arrives in 2025.
Lastly, for these that’re much less taking into consideration lap cases and need a long way more emotional enchantment, Porsche lately published the plunge-top 718 Spyder RS. We’ll be using it this week, so reach abet to City A.M. rapidly for our evaluate.
