Enthusiasts and buyers alike know that today, if you want a hardcore Porsche 911, you go for the GT3. But that wasn’t always the case.

In fact the first 911 GT3 didn’t come out until 1999. Before that it was all about the Carrera RS, like the one you see here.

This 1995 Porsche 911 Carrera RS 3.8 was the most hardcore atmospheric version of the 993, coming second on the totem pole only to the original GT2 that launched with twin turbochargers only two years prior.

Like the GT2, it was built as a homologation special in order to allow Zuffenhausen to field a similar version on the racetrack. So the engine was bored out to 3.8 liters and fitted with a variable intake system, forged pistons, dual oil coolers, and more, resulting in a 300-horsepower output that exceeded any other naturally aspirated road-going 911 to that point.

The Carrera RS 3.8 wasn’t just about the engine, though – it was also lightened considerably, jettisoning in the process the power locks, seats, mirrors, and windows, as well as the speakers, air bags, sound insulation, rear defroster, and headliner. Thinner glass replaced the heavier windows, lightweight seats were fitted, and some body panels refashioned out of lightweight aluminum – all of which helped get the weight down to 1,280 kilograms (2,822 lbs), which was even lighter than the GT2.

As if none of that were enough, the RS 3.8 also benefited from an upgraded suspension, strut brace, adjustable roll bars, antilock brakes from the Turbo, and a limited slip differential. This particular example – one of only 1,114 made and never offered in America – also features the Club Sport aero pack, making it even more desirable. That’s why RM Sotheby’s anticipates that, with less than 25,000 kilometers on the clock, it will sell for about $500k (give or take $50k) at its Santa Monica auction later this month. Whoever places the top bid will be in for one heck of a ride. Photos by John Bazay courtesy of RM Sotheby’s.
