The rarest 964 RS variant was the awesome 964 C4 Lightweight. Known as the 964 Leichtbau it made use of surplus parts from 953 Paris-Dakar project. A handful of specially prepared lightweight 911s were fabricated by the Porsche factory and called the Carrera 4 RS Lightweight. The idea was to combine the 964 RS body with the more sophisticated all-wheel-drive system from the 959.

The 964 C4 Lightweight was powered by the same 3.6 liter flat six as the normal 964 RS, but was fettled to produce 300 hp (the 964 RS made do with 260 hp). Porsche engineers freed the extra horsepower by removing the catalytic converters and mufflers. A special competition clutch and single-mass flywheel were mated to the car’s close-ratio five-speed manual transmission.
