Porsche 911 Carrera 2 RS (964) ~ 1991-1992
A worthy successor to the 1973 RS, the new car was named 'Carrera 2 RS' and like its predecessor, weight reduction was paramount, especially in the case of the Sport (also known as Lightweight) version. Around 120kg was shaved from the car by deleting 'luxuries' such as a sunroof, electric windows, electric mirrors, rear seats, door pockets, and much of the sound insulation, while the side windows were made of thinner (and therefore lighter) glass and a simple two-speaker radio/cassette player was optional. Seats were lightweight Recaros and there were simple, racecar-style pull-straps on the doors.
Further weight was saved by the fitment of magnesium alloy Cup wheels, which were 17-inches in diameter, 7.5-inches wide at the front and 9.0-inches at the back.
The lightening process went a long way to make the RS feel faster and more nimble than the standard Carrera, but it was only part of the story. The engine was given a modest 10bhp power boast to 260bhp simply by tweaking the engine management system, while a lightweight, solid flywheel helped the engine to be more responsive and was linked to a harder clutch plate.
The power went through a G50 five-speed gearbox modified with revised ratios, stronger synchromeshes, shorter gearlever and a limited slip differential.
The suspension was lowered by 40mm to give the car a more purposeful stance and to improve handling. The latter was further enhanced by rigid rear swing arms, larger antiroll bars (24mm front and 18mm rear), front strut-brace, and much stiffer springs and dampers. The brakes, too, were uprated with a mix of 911 Turbo front discs and Carrera Cup rears.
The bodyshell looked like the standard Carrera item, but was seam-welded for added strength and rigidity, while the wheel-arch returns were rolled to give clearance for the larger wheels and tyres. At the rear, a new-style lightweight bumper was used with protrusions each side of the numberplate to house the lights for said plate. The bonnet was made of lightweight aluminium instead of steel.
The RS in stripped out Sport guise was a no-compromise machine that was most suited to track use, which is why Porsche also offered a Touring version. This was much closer in spec to the standard Carrera 2, but retained the thinner side window glass and aluminium bonnet of the Sport, not to mention the uprated engine and suspension. However, it still didn't have rear seats. The weight saving was around 50kg compared with the standard car, but the Touring didn't offer the raw excitement of the Sport.
It is believed that Porsche sold 2051 Carrera 2 RS cars, and just 76 of these were Touring versions. Some say that the Sport is too extreme for road use and they could be right if you want a car for everyday use, but for weekends and trackdays a Carrera 2 RS is hard to beat, and still more affordable than the 1973 version.
