The 911 GT3 RS debuted in 2003, toward the end of the 996-chassis generation of the 911. It was an even more track-oriented, limited-production version of the already hyper-focused 911 GT3, itself based on the 911 GT3 Cup racecar. Produced as a street-legal model to comply with homologation rules for competition, the GT3 RS represents the ultimate intersection between production car and race car. Its alphanumeric name even says it: The “GT3” designation indicates a competition class introduced in 1994, while the “RS” moniker stands for rennsport, “racing sport” in German. Distinctive, color-matched side decals and wheels give a nod to notable Porsches from the past, such as the Carrera 2.7 RS of the early 1970s.

The GT3 RS was lighter than the standard GT3, thanks in part to a polycarbonate rear window and carbon-fiber hood and rear wing. The GT3’s 3.6-liter flat-six was distinctly different than the engine used in standard 911s. Known as the “Mezger” engine after its designer Hans Mezger, it was based on that of the 911 GT1 race car, which finished first and second at the 1998 24 Hours of Le Mans. In the production 911 GT3, the engine featured water-cooled cylinder liners and heads, lightweight forged pistons, titanium connecting rods, a dual-mass flywheel, and a racing clutch. The RS version was additionally fitted with modified cylinder heads featuring unique intake and exhaust ports elevating output to a claimed 376 horsepower. The GT3 RS chassis featured front and rear adjustable control arms, progressive springs, and stiffer dampers. Porsche’s lightweight ceramic composite brakes were optional and offered superior heat dissipation.

The subsequent 997-chassis version of the GT3 RS, an example of which is offered here, launched in 2006. Output for the 3.6-liter engine increased to 415 horsepower, while aerodynamics took a huge leap forward with redesigned bodywork featuring a front spoiler and adjustable rear wing that together generated zero aerodynamic lift. As with the previous version, the 997-chassis GT3 RS was both wider and lighter than the standard production GT3. This generation of 911 GT3, in both standard and RS form, was also the first production GT3 model to feature Porsche Active Suspension Management (PASM) electronic active damping. For the 2008 model year, Porsche is believed to have produced just 803 examples of the 911 GT3 RS.

This US-specification GT3 RS completed production on 1 October 2007 and left the factory finished in Green (J5), a highly distinctive paint scheme commanding an extra $3,140. The black full-leather interior, a $2,995 option, was specified from the factory with various trim pieces finished in the exterior color at a cost of $6,915, including parts of the center console, doors, and dashboard. The extensive list of factory options also includes various other desirable and costly features, such as Ceramic Composite Brakes ($8,840), the Sport Chrono Package Plus ($690), Porsche Communication Management with Extended Navigation ($3,110), and the Bi-Xenon Headlamp Package ($1,090). In total, the discriminating original owner of this well-specified 911 GT3 RS spent an additional $31,090 in options to customize this car down to the finest detail, going so far as to stipulate red taillight lenses ($640), specific exterior trim finished in Green, an aluminum footrest ($250), and the lid of the center storage bin finished in Alcantara with embossed Porsche logo ($490).

In July 2022, the car was professionally serviced, having the oil, fluids, filters, belts, and spark plugs changed. Crucially, a recent diagnostic report indicates that the car showed no over-revving in any of the six tested ranges.

Driven only 3,635 miles from new as of cataloguing time and with what is possibly among the highest original manufacturer suggested retail prices for this generation of 911 GT3 RS when new, this spectacular example in a rare color has been well-preserved its entire life and is ready to be cherished by its next owner, whether it be pampered to preserve its excellent condition, or flogged flat-out on a circuit, as it was made to do.
