1974 Porsche Carrera RSR 3.0 Coupe

For the 1974 racing season, the RSR was given a new type 911/75 engine boasting 330 horsepower, displaced 2,993cc, and had slide-valve mechanical fuel injection. There were four-piston 917-type brakes, magnesium center-lock wheels, a remote oil cooler, and an 80% locking limited-slip differential. The engine was paired with a Type 915 five-speed manual transaxle and the suspension was independent with double-wishbones, coil-over shock absorbers, and anti-roll bars. The body incorporated G Series bumpers, and wide front and rear fenders that were vented to allow heat to dissipate from the brakes. A larger rear spoiler was homologated for the 1974 model year and significantly increased downforce at speed.

During the 1974 season along, the 3.0 RSR had GT victories at Monza, Spa, Nürburgring, and Kyalami. It also captured the IMSA Camel GT Championship, the European Hill Climb Championship, and national championships in Switzerland, Sweden, Holland, and France.

This particular 1974 Carrera 3.0 RSR was delivered new to dealer Hahn Motorfahrzeuge of Stuttgart, and soon sold to another Porsche dealer, Enzo Boldrin of Italy. Mr. Boldrin sold the RSR to Conte Girolamo Capra from Vicenza, Italy who raced it during the 1974 and 1975 seasons. It had been delivered white but Capra had it painted yellow and raced it at events which included Monza and the Targa Florio, among many other races and hill climbs. Among the accolades achieved was a 6th overall in the 1975 and 1975 editions of the Targa Florio, and 5th Overall in the 1975 Monza 6 Hours.

Carlo Tormene of Italy acquired it in 1976 and his history with the vehicle is not fully known. It may have placed 4th Overall in the 1977 Rally 1000 Miglia in Brescia, Italy while with Tormene.

Around 1985, the RSR was sold by Tormene to Ernst Schuster of Germany who sold it in 1987 to Albert Obrist. In 1987, Obrist sent the RSR to Siggi Brunn for restoration in Heidelberg, Germany, and the Porsche remained in Brunn's care until 2004. During his ownership, a proper 3.0-liter type 911/75 RSR engine, no. 6840163, was acquired for the car.

In 2006, the Porsche was sold by dealer David Mohlman to Lloyd Hawkins in a disassembled state, consisting of the body, doors, hood, fenders, deck lid, engine, and gearbox. Mr. Hawkin's in-house crew restored the car in the ensuing years as the Kremer/Brambring RSR. With assistance from historian John Starkey, it was discovered that this Porsche was the Girolamo Capra RSR.
