The 1993 Porsche 964 Carrera 3.8 RSR was the final version of the lightweight Carrera RS introduced two years earlier. Designed for privateers to enter international GT races, the 964 RSR was the right car for the times. A perfect match to international rules that governed GT racing cars, the RSR became one of the most successful competition versions of the air-cooled 911 in Porsche’s history, and just 51 are believed to have been built. Examples seldom come to market, especially with such appealing history and authenticity as this car.
Both the 1993 24 Hours of Interlagos and Spa were won outright by 964 RSRs, and when production cars returned to Le Mans that year after an eight-year absence, they dominated the GT category. RSRs took the first four places in their class at Le Mans, with legendary Porsche driver Jürgen Barth finishing 15th overall.
Other RSR entries swept the first four GTU places in the 24 Hours of Daytona, with the lead car finishing third overall. Another won its class at the 12 Hours of Sebring and was fifth overall. Such GT-class domination hadn’t been seen in years, and is a tribute to the impeccably engineered RSR’s performance and reliability. The model remained competitive in 1994, and scored class wins through 1995, before Porsche turned its attention to the 993-based GT2 for international events.
Very different from the standard road car, the RSR’s engine was bored out to 3.8 liters, with pistons and intake system reworked for more horsepower and torque. The Turbo-style bodywork was fitted with wider wheels, aluminum doors, and front deck, even more aggressive fiberglass rear deck and spoilers, and suspension settings from the Carrera Cup cars. The car’s total weight was 2,500 lbs. – about 350 lbs. lighter than a standard car. The RSR had a base price when new of $160,500, with the only options being an on-board jacking system, center lock wheels, and an optional passenger’s seat. It was expensive, but it was ready to race, and win.
Porsche claimed 320 bhp for the M64/04 engine, but Car and Driver magazine thought the figure typically conservative and calculated the true output was more like 375 bhp, considering that 0–60 mph took only 3.7 seconds, which was faster than a Ferrari F40. The bigger brakes developed from the Turbo S could stop an RSR from 70 mph in 150 feet.
The RSR was available in PTS (paint to sample) colors, and they were typically ordered in vibrant shades. This car was delivered in Speed Yellow with a black interior to Kevin Kirby of Sioux Falls, South Dakota, in December 1993. Correspondence between Mr. Kirby and the factory, including a note from Mr. Barth, is included with the sale; the factory informed Mr. Kirby that the RSR was a competition car, and could not be road-registered.
Mr. Kirby kept the RSR until September 1999, when it was acquired by the first of two Japanese owners, Kazuo Mizushima, whose business address was in Tokyo. After an unknown period of time, he sold the RSR to Yasuto Yamada, who also owned a business in Tokyo. One of the two Japanese owners registered the car for the road, changing the side windows. Original windows are included, along with an exhaust, and center hub covers. The RSR was never raced in Japan, but reportedly was displayed at the track in advance of sports car races.
In 2007, this RSR was sold to Edmond Harris of South Leigh, Witney, Oxfordshire, in England. Harris kept it until January 2008, when it was acquired by the consignor. At that time, the odometer indicated 2,600 km.
The consignor entered into correspondence with Porsche archivist Jens Torner, acquiring a Porsche Certificate of Authenticity, numerous other documents, and confirmation from Torner that the engine in the car is the original unit. This car’s odometer, at the time of cataloguing, indicated approximately 4,000 km, and it is described by the consignor as having never been raced, crashed, or restored.
Due to the model’s incredible international competition pedigree, the 964 RSR is one of the most desirable and collectible factory racing variants of the 911. The chance to purchase such an unaltered example of this icon offers an inspiring opportunity.
