1991 Porsche 911/964 Carrera 4 - Lightweight
|Engine Displacement||3.6 cc|
Following in the rich motorsport heritage of the extreme limited edition race and rally cars Porsche has produced over the years, such as the 911R, the Homologation 911 2.7RS and the 911SCRS, the 964 Carrera 4 Lightweight (Leichtbau) is an extremely rare and special model. The car we have on offer here is number 20 of only 20 built.
Conceived and built by Jurgen Barth of the Customer Sports Department at Weissach, the car was designed to be a stripped out racer that would be easy to import into the USA, as Porsche had many problems trying to federalise the 959 that came before it. Barth envisioned a single make race series created especially for the Leichtbau, and forged ahead to make the car ready for export, in the process creating the rarest 964 of all.
Starting with a seam welded shell, Barth specified aluminium doors and front lid, fibreglass engine lid/spoiler and Plexiglass windows all round to pare the curb weight to a minimum. The weight saving continued inside with all insulation and carpeting removed, and replaced with lightweight Recaro racing buckets with harnesses, RS style door cards and a special Momo steering wheel. Cup car adjustable suspension was fitted, along with a chassis strut brace and hand made Matter roll cage. Even the oil tank is mounted within the wheelbase for better chassis balance, with a side mounted filler flap harking back to the 911s of 1972.
The drivetrain consists of an RS spec engine with unsilenced separate racing exhaust manifolds, a close ratio 5 speed gearbox with a single plate clutch and single mass lightened flywheel, and the manually adjustable mechanical all wheel drive system from the Paris Dakar winning 953 of 1984. Ready to race, the car weighed 1,090kg, around 150kg less than an RS.
Unfortunately a race series was not forthcoming for the Leichtbau to compete in, and the Carrera Cup took over as a worldwide forum for the 964RS, of which 2,282 ended up being produced. With only 20 cars made, the Carrera 4 Lightweight is a car that many collectors have never heard of, let alone seen available on the market.
