In 1992 the Special Wishes Department at Porsche announced the very exclusive 964 Turbo S Leichtbau. The first ever lightweight Turbo to be produced by Porsche.
In order to reduce the overall weight of the car sound proofing and undercoating were limited to minor amounts, power windows and power steering were removed, rear seats were removed. Fibreglass reinforced carbon composite panels were used for the doors, bonnet and rear wing. Thinner glass, RS bucket seats and RS door cards completed the weight saving. The Turbo S Leichtbau is 396 pounds lighter than a standard 964 Turbo.
In addition to the weight saving. Porsche also enhanced the engine giving the Turbo S Leichtbau an additional 61 horsepower over the standard 964 Turbo. This was achieved with more aggressive camshafts, new injection valves and more boost pressure.
The Turbo S Leichtbau has various handling and performance enhancements from the standard 964 Turbo. The car was lowered by 40mm, has upgraded brakes, 3 piece alloy wheels, an aluminium shock tower brace and a reinforced unibody. The fender vents were inspired by the infamous Porsche 959. Front bumper intakes were added to feed air to the oil cooler and front brakes. The Leichtbau also features a unique rear spoiler.
