Coupe
Chassis #: 9110300949
The Porsche 911 was introduced in 1964 and was soon followed by specific variants built at the factory for competition purposes and specifications that were unavailable through the order of Sport Purpose options alone. Porsche released a modified version of its 911 in 1970, in both rally and road race configurations, internally known as the 'ST.' No two cars were exactly alike, but most wore wider fender flares in the back (and sometimes in the front), and were given a slight increase in engine capacity. Thin-gauge sheet metal was used to help reduce overall weight, and a fiberglass hood and engine lids were installed. Other weight saving features including a lack of undercoating and soundproofing materials.

Privateers and the Porsche factory raced the 911 ST successfully in a variety of events, with wins in 1970 at the Tour de France Automobile and 36 Hours of Nürburgring, among other victories.

This particular example was a Works racing car, and a factory support car. It was originally powered by engine number 6301294, and was completed on February 3rd of 1970, and retained by the Porsche Sport/Presse department. It was given special gear ratios, a rally exhaust, 40% limited slip differential, and 100-liter fuel tank. It was prepared for 1970 Austrian Alps Rally, where drivers Björn Waldegård and Lars Helmer would drive it to its first victory in its maiden competition outing. It was then used as a service car for the 1970 Acropolis Rally by Jürgen Barth.

For its next outing at the RAC Rally England, it was given flared front wheel arches. Gérard Larrousse and Mike Woods drove it to 6th Overall. Mr. Barth used it as a service car during the 1971 Monte Carlo Rally, after which it was sold by Porsche to its first private owner, factory driver Gérard Larrousse. Mr. Larrousse, along with Louis Meznarie, entered the car in a number of events in 1971, oftentimes with Barth and others as drivers.

After a race at Magny Cours in May 1971, the car was painted in the Shell psychedelic yellow-and-red color scheme.

For the 1971 Tour de France, Larrousse entered this 911 ST for Barth and co-driver Jose Dolhem. During the event, the flywheel shook loose on the engine while racing on the Circuit Montjuic and was unable to be repaired, forcing its retirement.

On February 29, 1972, the car was sold to racing team owner Louis Meznarie. Its next owner, Philippe Burlet, is believed to have acquired the car around 1974. A later owner is belvied to be Willi Holzentahl of Germany, who sold it to American Porsche racer and enthusiast Roy Walzer circa 1997. Walzer had the car delivered to Jim Newton at Automobile Associates of Canton in Canton, Connecticut. At the time, the car was a roller without an engine and had damage to the right front of the car. A restoration was undertaken and the body was restored with fiberglass flares. A 2.5-liter short-stroke racing engine was sourced from Greg La Cava, and a modern fuel cell and fire system were installed for safety.

In 1998, Mr. Barth was reunited with the car and raced it at the Monterey Historics, placing 2nd behind Hurley Haywood in a Brumos 914/6. Barth drove the car for Walzer again in the 2013 edition of the Monterey Motorsports Reunion, placing 8th after an electrical problem forced him to start from the back.

The current owner acquired the car a short time later. Since then, Mr. Barth has compiled a very extensive report on the vehicle's history.
