History of the Clubsport
1987
Porsche unveils the 911 Carrera Club Sport, a lightweight variant of the 3.2 Carrera. Upgraded Bilstein shocks were included, and the luggage compartment and decklid lights were removed to save weight. A limited slip differential, optional for the base 911 at the time, was included with the Club Sport package. Although the specifications of the engine were officially unchanged from the base 911, the engine is reported to include hollow intake valves, a modified intake, higher RPM limit, and stiffer engine mounts. Club Sport engines of the time are reported to put out 245bhp, compared to the 231bhp of the base 3.2 Carrera.

To save weight, The Club Sport package removed a significant amount of interior amenities. The rear wiper, fog lights, and headlight washers were all discarded. The rear seats were replaced with carpet. Luxuries such as central locking, electric windows, sound insulation, the radio, and the passenger sun visor were all removed. As a result, top speed increased from 150mph to 156mph, and the 0-60 time decreased from 5.5s to 5.4s.
