2019 Porsche 718 Cayman Manthey Gt4 Clubsport

Has only done 900klm of light track days, zero accident damage.
This Porsche 718 Cayman GT4 Clubsport is an exciting mid-engined race car, offered in ‘Competition’ guise, which is focused on national and international motor racing.
Power comes from a 3.8-litre flat-six, producing 313kW / 425hp, driving the rear wheels through a six-speed dual-clutch automatic paddle shift transmission and a mechanical differential.
Based in Newcastle, New South Wales, this example is offered from the custody of its second owner, and represents a rare opportunity to purchase a GT4 Clubsport without the factory wait time.

EQUIPMENT AND FEATURES

The 718-generation Cayman GT4 Clubsport is faster and nimbler than its predecessor, and was built with a focus on the sustainable use of raw materials. It marks the first ever production race car to feature body panels made of natural-fibre composite material, understood to be sourced primarily from agricultural by-products such as flax or hemp fibres, and which features similar properties to carbon-fibre in terms of weight and stiffness. The remainder of the body is aluminium-steel composite. The car reportedly tips the scales at 1,320 kg. Its lightweight spring-strut front suspension is taken from the 911 GT3 Cup, while stopping power comes from 380 mm steel brake discs. Equipment includes a welded-in FIA-certified roll cage, an escape hatch, Recaro bucket seats and Schroth six-point harnesses. It rides on one-piece 18-inch forged light-alloy wheels, shod with Michelin racing tyres. As a ‘Competition’ variant, this car features a raft of race-focused details, including three-way adjustable shock absorbers, a 115-litre safety fuel tank, a brake balance system, an integrated air jack system, an automatic fire extinguishing system and a highly adjustable quick-release steering wheel adopted from the 911 GT3 R. This example is wrapped in a white, grey, yellow, and black livery, with a Porsche windscreen decal, and sponsorship logos from TAG Heuer, Michelin, Mobil1 and Hugo Boss. Various spare parts will be included, including a mesh guard set for the air intake, two spare wheel sets new with TPMS equipment, racing brake fluid, front and rear ‘sprint version’ brake pads 2 sets new, front and rear brake discs 2 sets new. One set of slicks, one set of transport tyres and two new sets of Yokohama A050.
