After just a couple years of racing, Enrst Fuhrmann’s legendary four-cam boxer engine was deemed ready for production use, and by 1955 it was made available in the 356A Carrera, named after the grueling and deadly Carrera Panamericana road race. This incredible collection from Garage44 presents a thorough cross-section of the Carrera program as it existed in the late 1950s and early ’60s. Each is powered by a plain-bearing version of the four-cam engine, and each represents a different facet of the Carrera ethos, which in many ways has been the guiding principle for nearly all Porsches—equally at home on track or in traffic, and able to switch between the two with ease. The 356A Carrera 1600 GS Coupe is the more refined of the trio, the 356B Carrera 1600 GT Coupe aimed principally at competition, and the 356A Carrera 1600 GT Speedster a stripped down, simplified driving machine ready for any (dry) road or circuit. Any one of them would be cause for excitement on its own, and taken together they illustrate a progression from high-speed touring to focused track use during one of the most technically ambitious periods in Porsche’s early history.
Each comes with documents attesting to its provenance, and all received mechanical attention from Speedsport Tuning’s four-cam wizard Jeff Adams. They have been refurbished and refinished in their factory-specified colors. The cars from the 1-2-3 4-Cam collection will begin posting on Monday, September 14, and links to live auctions will be added to this post as they become available.
1959 Porsche 356A Carrera GT Speedster
Chassis 84945 is said to be one of 14 Carrera GT Speedsters built with the Type 692/3 plain-bearing four-cam engine, and as a 1959 car it is among the last of the Speedster bodystyle. It is finished in its Silver Metallic (608), as originally specified, over a black interior. As a GT-specification Speedster, it features the lightweight and competition-oriented equipment that distinguished these cars from standard production examples, including aluminum opening panels, aluminum/steel wheels, an 80-liter fuel tank, and 60mm front drum brakes.
This car underwent a refurbishment in which body and metalwork were performed by Tom Caruso of Contour Metal, while the engine and mechanical systems were rebuilt by Jeff Adams at Speedsport Tuning, who learned the art of four‑cam tuning from a Porsche technician trained on these engines in‑period by the factory. Its current Type 692/3 engine is no. 95016—just one digit off from its original engine, which was no. 95017. The car was Best in Class at the 2021 Greenwich Concours and scored 295.1 out of 300 points at the 2022 Porsche Club of America Parade Concours. It also received the Gmünd Award and the prestigious Honorary Judge’s Award, making this Speedster a blue chip bathtub good for show or go.
1960 Porsche 356B Carrera 1600 GT Coupe
Chassis 110858 is one of less than 50 Carrera GT Coupes produced for the 1960-61 model years and retains a numbers-matching Type 692/3 plain-bearing four-cam engine, no. 95072. The Ruby Red (702) over black car is equipped with the important GT features associated with Porsche’s competition-oriented Carrera program, including aluminum opening panels, Plexiglas windows, aluminum and steel wheels, an 80-liter fuel tank, and 60mm front drum brakes. The GT Coupe is accompanied by FIA Historic Technical Papers and has an extensive European vintage racing history spanning the 1980s and 1990s, including competition at venues such as the Nürburgring, Monza, Zolder, and Mainz-Finthen.
In 2019, it was selected by Porsche Cars North America for its corporate display at the Amelia Island Concours. In early 2026, the car received a comprehensive mechanical service by Jeff Adams and Speedsport Tuning, further adding to the appeal of this highly specified and well-documented Carrera GT.
1959 Porsche 356A Carrera 1600 GS Coupe
Chassis 108186 is one of just a few dozen Carrera GS Coupes produced for the 1959 model year and was delivered new through Sonauto in Paris. It is finished in its factory-correct Silver Metallic (608) over a special-order red interior and is powered by engine 93133, replacing its original engine (no. 93116). The replacement engine is a Type 692/2 plain-bearing four-cam, said to be the same type as that originally specified. The Grand Sport moniker indicated a more refined touring intent, which at the time meant amenities like a heater, cushy leather seats, carpets, map pockets, and chrome door pulls.
This example received a high-quality restoration some years ago and presents quite well today. Its suspension and engine have been expertly set up by Jeff Adams at the aforementioned Speedsport Tuning.
Those are the cars of the 1-2-3 4-Cam collection. We’re excited to watch the action unfold!
