A conservative estimate was that these cars were pumping out 240bhp although Porsche always played down any horsepower gains to avoid the bureaucracy involved in homologating a new variant. To save weight, Porsche junked many of the luxuries fitted as standard to the normal 911. Gone were the electric windows, the sunroof, rear wiper, central locking, radio, rear seats and air conditioning. The sound insulation, passenger sun visor and even the lockable oddments bin were also discarded. No PVC underseal was applied and this meant the anti-corrosion warranty was reduced from ten years to just two. Simplified door trim was installed along with a new rev counter, a short-shift gear lever and a carpeted rear shelf where the rear seats used to be. The majority of Club Sport’s were finished in Grand Prix White with red ‘Carrera CS’ scripting down each side, red ‘CS’ decals on the front lid and red wheel centres. Customers could opt for the garish decals to be left off though and black or white-centred wheels were also available. Unsurprisingly, with more power and 38kg less weight to lug around, the Club Sport instantly became the quickest normally aspirated 911 available, 0-60mph requiring a mere 5.5 seconds whilst top speed rose to 156mph. Built for just two years, production was discontinued in September 1989 after 312 had been built, 50 of which were right-hand drive. In addition to the 312 Club Sport Coupe’s, a solitary Targa was also manufactured along with 28 US cars that featured standard American-spec 217bhp engines.
