No Reserve: 1959 Porsche 718 RSK Replica

This 1959 Porsche 718 RSK roadster is a racecar replica that was produced by Thunder Ranch set up on a space frame chassis, developing power from a rebuilt 1,498cc flat-four paired with a 4-speed manual transaxle. Coil spring underpinnings provide balance and composure while the interior offers vinyl upholstery in the cockpit for two. Finished in Burgundy Metallic over a tan vinyl interior, this replica is now offered with service records, an extra set of wheels, and a clear Alabama registration in the seller’s name.

Launching in 1958 in Formula races in Europe, the original Porsche RSK was designated as purely a racecar, drawing its name from a combination of Rennsport and K, the K being a descriptor for the front suspension configuration. Thunder Ranch in El Cajon, California, now known as Rock West Racing, produced the framework for a street-legal replica of the racecar by adapting a TR 550 frame, powder coating it, and then adding a blended polyester body to the frame with adhesive and rivets. This custom-built example rides on a space frame chassis and is painted Burgundy Metallic, accented by gold-finished Porsche logos and displaying covered headlamps, quad taillights, and a single-outlet exhaust.

Chrome-finished racecar wheels are currently mounted on this replica, and the sale includes an extra set of wire wheels. The suspension setup consists of a watt linkage and coil springs.

The interior is fitted with tan vinyl bucket seating for two, contrasted by brown piping.

Instrumentation includes a speedometer and auxiliary gauges. The odometer reads 2,475 miles, which reflects mileage driven since completion of the build.

The rear-mounted 1,498cc Volkswagen flat-four was completely rebuilt in early 2021 according to the seller. Power is directed via a 4-speed manual transaxle.
