Combining the classic styling of the 356, F-Body, and G-Body 911s with the performance and technical advancement of the 964, this 1992 Porsche Carrera 4 underwent a custom “GS 964” restoration by GS Manufaktur in Germany between 2020 and 2021. This Coupe was outfitted with new carbon composite bodywork, custom trim, and a tailor-made interior along with upgraded brakes, suspension, and a 3.8-liter RS-spec engine. Built with no expense spared and exhibiting unprecedented attention to detail, this one-of-a-find GS 964 is now being offered for auction by its creators out of Germany.
Designed in-house and adapted from a hand-shaped clay model, the CAD-developed bodywork is made entirely from carbon fiber including the front and rear bumpers, spoiler, rocker panels, fenders, and hood. The original metal roof panel, doors, and rear decklid were retained for safety purposes. The body is finished in a custom Grey Blue paint color and adorned with GSM-developed trim including air intake grilles machined from a single block of aluminum. The custom LED headlights were developed in-house by GSM and use a single bulb for both high and low beams. It rides on a set of GSM Fuchs Classic wheels with custom fabricated center caps and wears an application of clear paint protection film over the full exterior.
The interior has been completely redone in a combination of Dark Blue leather and Grey Blue Alcantara upholstery with classic square weave carpets lining the floors. The seller notes the cabin was expertly tailored by a German Porsche-certified workshop and that the gauges, radio, and A/C unit have all been replaced or completely overhauled. The odometer was reset upon completion of the restoration and less than 3k kilometers have been driven since.
Producing a claimed output of 330 HP, the air-cooled flat-six engine in this 964 has been rebuilt to RS specifications with 3.8-liter pistons and cylinders as well as a custom dual-flap stainless-steel exhaust. Power is distributed to all four wheels through an overhauled G50 5-speed manual gearbox with a single-mass flywheel. The suspension has been upgraded with Bilstein PSS10 coilovers and the stopping power has been improved with 993 “Big Red” Brembo brakes. The seller notes two services have been completed since the completion of the build and that another maintenance check will be completed prior to delivery for its next owner.
This sale will include a clean title.
