Porsche 550 Spyder Replica

This Thunder Ranch 550 Spyder replica was built in 2003 and was purchased by the seller on BaT in November 2022. Subsequent work included replacing the engine with a 2,332cc flat-four, installing a cable shifter for the four-speed manual transaxle, replacing the red vinyl upholstery, adding red vinyl stripes to the silver exterior, and installing 15″ wide-five aluminum wheels, a banjo-style steering wheel, and replacement brake rotors. Other equipment includes a driver-side helmet fairing, a black removable soft top with side curtains, a red tonneau cover, and #55 roundels. This 550 Spyder replica is now offered with spare parts and a clean California title in the seller’s name listing the car as a 1955 Porsche. The fiberglass body covers a tube-frame chassis and is finished in silver, with the red accents and roundels having been added under current ownership. Exterior features include a removable black soft top with side curtains, chrome-finished windshield and headlight trim, a driver-side helmet fairing with an integrated headrest, dual fender-mounted Talbot mirrors, twin engine-lid grilles, and a single center-exit exhaust outlet. The removed roll bar is included in the sale. Work since the seller’s purchase included replacing the headlights, taillights, and windshield. The 15″ wide-five aluminum wheels were installed since 2022 and are mounted with 195/60 front and 205/60 rear BFGoodrich Radial T/A tires. Stopping is provided by discs at each corner, with replacement rotors installed at all four corners since the seller’s purchase. The cabin features fixed-back bucket seats that have been retrimmed in red along with matching carpets and body-color surfaces. Equipment includes a red tonneau cover, latch-and-link lap belts, and a dash-mounted rearview mirror. The carpeting in the footwells is discolored. The handbrake was replaced by the seller. The banjo-style steering wheel was added under current ownership and fronts a 130-mph speedometer, a 6k-rpm tachometer, and a combination gauge. The five-digit odometer shows 3,800 miles, approximately 800 of which were added under current ownership. The air-cooled 2,332cc flat-four was installed in 2024 routes power to the rear wheels through a four-speed manual transaxle that received a new cable shift mechanism since 2022. Other work during that time included adding an external oil cooler and fan. The engine oil and transaxle gear oil were changed in preparation for the sale, and the Weber carburetors were also tuned at that time. A powder-coated exhaust system has been installed. An oil leak is noted from the bottom of the oil sump.
