The Porsche Cayman GT4 Clubsport already made its Asian debut at Sepang in November, but the car that Porsche distributor Sime Darby Auto Performance (SDAP) wheeled out during a press event at the Sepang International Kart Circuit yesterday wasn’t any other Clubsport, but one belonging to SDAP itself.
That’s right, the company will be participating in a number of motorsports events across the region throughout 2017 with this car, which comes in a searing chrome and fluorescent green livery. Eagle-eyed readers will also notice that the car is actually badged the Cayman GT4 Clubsport MR, with the “MR” standing for Manthey Racing.
That’s because the car has been tweaked by the German World Endurance Championship (WEC) team to be eligible for GT4 racing – and hence able to compete in series like the 2017 Blancpain GT Asia series. The changes are fairly far-reaching and include carbon fibre bonnet and doors, a larger rear wing for extra downforce, a polycarbonate windscreen and a steering wheel control unit.
Changes under the skin too, such as an endurance-spec 100 litre tank, two-way adjustable race suspension, a front anti-roll bar, an adjustable brake balance lever and a driveshaft spacer to ease rear geometry set-up. The car also comes with distinctive (and optional) quad auxiliary LED lights for 24-hour racing.
Otherwise, it’s pretty much a standard Clubsport, with lightweight aluminum-steel composite construction, 18-inch forged alloy wheels as well as a stripped-out cabin with an Alcantara Porsche motorsport steering wheel, a Recaro P1300 GT race seat, a six-point racing harness and a fully-integrated FIA-spec roll cage.
Under the rear hatch sits a 3.8 litre naturally-aspirated flat-six that produces 385 hp at 7,400 rpm and 420 Nm of torque from 4,750 to 6,000 rpm. Unlike the standard GT4, the Clubsport ditches the six-speed manual gearbox for a six-speed PDK dual-clutch transmission with paddle shifters.
MacPherson strut front suspension and a lightweight rear strut suspension with transverse arms are fitted – the same as the 911 GT3 Cup – as is a race-specified mechanical rear-axle locking differential; the steering retains electromechanical assistance. Braking is handled by 380 mm grooved steel discs all around, clamped by six-piston callipers in front and four-piston ones at the rear.
