Daytona Classic 24, November 2014 (4th in Class)

Looking to compete in FIA’s Group 4 category, Special Grand Touring Cars, Porsche built an all-out racing model based on the Carrera 2.7 RS – the 2.8 RSR. These cars were developed strictly for competition use and featured a twin-plug engine, upgraded brakes, modified suspension, and lightweight bodywork.

The 2.8 RSR made its competition debut at the 1973 24 Hours of Daytona, where Peter Gregg and Hurley Haywood drove it to an outright victory. From there, RSRs went on to win at the 12 Hours of Sebring and proved victorious at the final running of the legendary Targa Florio. In the 1973 European GT Championship, the 2.8 RSR was the car to beat, winning six of nine rounds.

For 1974, Porsche significantly improved the RSR platform and offered a revised, road-going Carrera 3.0 RS. With a new type 911/75 engine, the 3.0 RSR boasted 330 bhp and weighed in at just 950 kg. The new model featured four-piston 917-type brakes, magnesium center-lock wheels, and a strengthened transaxle with splash lubrication, a remote oil cooler, and an 80% locking limited-slip differential.

The body of the new 3.0 RSR was highly modified as well. Its G Series bumper shape gave it a distinctive outward appearance and its wide front fenders, which ended abruptly before the doors, allowed for heat to dissipate from the brakes. The rear fenders were also widened and were vented both front and rear. A larger rear spoiler was homologated for the 1974 model year and significantly increased downforce at speed.

The 3.0 RSR was an outstanding racing car and remained competitive for nearly a decade after its introduction. In 1974 alone, the 3.0 RSR conquered GT racing with wins at Monza, Spa, Nürburgring, and Kyalami. It also captured the IMSA Camel GT Championship, the European Hillclimb Championship, and national championships in Switzerland, Sweden, Holland, and France.

As the ultimate evolution of the classic RS-RSR racing program, the 3.0 RSR is widely regarded as the Ferrari 250 GTO of the Porsche world. With just 54 examples built between 1974 and 1975, it is nearly as rare.

Of the 3.0 RSRs delivered to North America, this car, chassis 911 560 9115, is among the very best, as it possesses an outstanding six-season racing history and a fascinating, unbroken provenance.

According to the research of marque historian Jürgen Barth, this 3.0 RSR was constructed in Porsche’s racing shop in October 1974 and given production no. 104 7002. Originally finished in Grand Prix White, the RSR was ordered by Jo Hoppen of Volkswagen North America on behalf of his client, 18-year-old Héctor Alonso Rebaque of Mexico City.

Rebaque began his international racing career at the 1972 12 Hours of Sebring driving a Brumos-entered 914-6. From there, he quickly advanced to the more potent 911 RS and RSR models, which he often entered with fellow Mexican racer Guillermo Rojas.

Beginning in 1977, Rebaque began a notable career in Formula 1 with Hesketh Racing. In 1978, he established Team Rebaque, that ran Lotus-Cosworth chassis before fielding his own Penske-designed Rebaque HR100, late in the 1979 season. Between 1980 and 1981, Rebaque was a member of the Parmalat Racing Team and concluded his Formula 1 World Championship career with 41 starts and 13 points.

The debut of Rebaque’s 3.0 RSR set the tone for a promising racing career, capturing an outright win at the 1000 Km of Mexico City in October 1974. The Porsche’s first outing in 1975 took place at the 24 Hours of Daytona, where the Café Mexicano-liveried car was driven by Rebaque, Rojas, and Van Buren to an outstanding 9th Place finish. That year, 911 560 9115 achieved excellent results in Mexico, winning the Carrera de los Campeones and finishing on the podium in the endurance races at Mexico City and Monterrey.

Following a short 1976 season, in which the RSR was campaigned at Daytona and Zapopan, the car was stored in Rebaque’s warehouse in Mexico City. As a result, 911 560 9115 was spared the very hard life so many 3.0 RSRs suffered as they were constantly modified and developed over the course of long racing careers.

Finally, in March 1981, Rebaque sold his lightly used 3.0 RSR to noted Puerto Rican driver Diego Febles. Refinished in a livery similar to Febles’ other RSR (an ex-Team Brumos car), 911 560 9115 achieved solid results throughout the 1981 and 1982 seasons, with a win at Hollywood Speedway, a 9th in Class at Daytona, and a 1st in Class at Sebring.

At the end of the 1982 season, Febles sold the RSR to Bobby Heurtemate and Kikos Fonseca’s Latino Racing Team, which continued to race the Porsche through 1984. The aging RSR proved that it was still a force to be reckoned with, finishing 2nd in Class at Daytona, 4th in Class at Road Atlanta, and 6th in Class at Riverside. Following the 1984 season, the RSR was retired from racing and sold to Elias Chocron of Panama. By 1987, it had passed into the care of Jim Borsos, a resident of Anaheim, California.

Between 1988 and 1989, 911 560 9115 was restored to its original factory specification by highly regarded Porsche specialist Jim Torres of Burbank, California. Following this restoration, the RSR led a gentle life, residing in two private collections and making just one showing at the Monterey Historics in the early 1990s.

When acquired by the current owner, an Australian enthusiast and active vintage racer, the RSR was prepared for a return to racing. The car was entrusted to heritage Motorsports in Tampa, Florida, which recommissioned the Porsche, that had seen many years of relative inactivity. After being prepared to compete in the inaugural Daytona Classic 24 event, a rigorous test program was undertaken to ensure the car was fully ft for purpose and race-ready. As this work was being carried out, the RSR was inspected by Jeremy hall, a US representative for the FIA, and was subsequently issued its FIA Historic Technical Passport in March 2014.

The quality of this recent preparation was clearly demonstrated when the RSR competed at Daytona in November, running without fault and finishing with an outstanding 4th Place outright in Group B, for cars built between 1973 and 1982. Following this outing, the consignor reports with confidence that this historic Porsche is “fully race prepared, on the button, and fit for competition at the highest level.”

Presented today in immaculate condition, finished in its memorable 1975 Café Mexicano Daytona livery, and offered with current FIA papers, a Porsche Certificate of Authenticity, and reports prepared by Jürgen Barth and John Starkey, the Héctor Rebaque RSR is among the finest examples of the model to be found anywhere.

In his report, marque authority Barth confirms that 911 560 9115 “is an original car of the Porsche 911 Carrera 3.0 RSR Series” and states that, “the car makes a very good impression” and that “it is in very good condition and corresponds in every detail to the original factory condition.” Significantly, this RSR retains its original chassis number stamping, original type plate, a proper 911/75 engine, 915 gearbox, and the welded reinforcement gusset plates that are unique to these specialized competition cars.

Offered for public sale for the first time in its history, this outstanding 3.0 RSR would make an ideal entry for any number of historic racing events, including Le Mans Classic and Tour Auto, and it would be an absolute standout at marque gatherings like the upcoming Rennsport Reunion in September 2015. Not only is this exceptional Porsche a ticket to the most exclusive historic motoring events, its superb six-season international racing history, vibrant period livery, outstanding preparation, and intimate connection to Héctor Rebaque – one of the last great gentleman drivers in Formula 1 – place it among the very best examples of a rare breed.
