1990 Porsche 911 Carrera 4 Cabriolet 5-Speed

This 1990 Porsche 911 Carrera 4 cabriolet is finished in Grand Prix White over blue leather upholstery and is powered by a 3.6-liter flat-six that drives all four wheels through a five-speed manual transaxle. Equipment includes a dark blue soft top, 18″ Speedline-style wheels, H&R front lowering springs, a limited-slip differential, power-adjustable front seats, cruise control, and air conditioning. The car has been registered in Colorado and California, and it was sold on BaT in November 2022. Subsequent work is said to have included resealing the engine, reupholstering the seats, and fitting Bilstein shocks and a Continental stereo in addition to replacing the clutch, flywheel, air-flow meter, injectors, convertible top, carpeting, speakers, and tires. Purchased by its current owner in 2024, this 964 C4 cabriolet is now offered on dealer consignment in California with a clean Carfax report and a clean Colorado title.

The car is finished in Grand Prix White (908) and features a replacement dark blue convertible soft top installed after 2022. A matching top boot will accompany the car, and exterior details include a speed-activated rear spoiler, integrated fog lights, and heated and power-adjustable side mirrors. The top’s header latches are power-operated, while the top itself is raised and lowered manually. Photos showing blemishes on the bumper covers and mirror housings are provided in the gallery below.

Speedline-style 18″ wheels wear 225/40 front and 265/35 rear Continental ExtremeContact Sport tires produced in 2022. Anti-lock braking is handled by Porsche-branded calipers over ventilated discs, H&R lowering springs are said to be in place up front, and replacement Bilstein B6 front and rear shocks were reportedly installed after 2022.

The power-adjustable front bucket seats have been reupholstered in blue leather and are accompanied by a color-coordinated dashboard, center console, door panels, and rear seats. Replacement carpeting has been fitted, and additional appointments include electrically adjustable lumbar support for the driver as well as air conditioning, cruise control, power windows, a Continental multimedia stereo, and replacement speakers.

The leather-wrapped four-spoke steering wheel frames VDO instrumentation consisting of a central tachometer with a 6,800-rpm redline as well as a 180-mph speedometer, a Quarz analog clock, and gauges for oil level, oil pressure, oil temperature, and fuel level. Cracks in the lens over the fuel- and oil-level gauges are depicted in the gallery. The six-digit odometer shows 57k miles.

The air-cooled 3.6L M64 flat-six was factory rated at 247 horsepower and 228 lb-ft of torque. Reported work since 2022 included resealing the engine and replacing the air-flow meter and fuel injectors.

Power is sent to all four wheels via a five-speed manual transaxle, and the Carrera 4 features a computer-controlled limited-slip differential. The clutch and flywheel were reportedly replaced within the last two years.
