The Carrera RS is a lightweight variant of the Carrera built in 1995 and 1996. It features a naturally aspirated 3.8-liter engine generating a maximum power output of 300 PS (221 kW; 296 hp) achieved by the use of lightweight forged pistons, dual oil coolers, big intake valves, Varioram variable-length intake manifold, a modified Bosch Motronic engine management system, and lightened rocker arms. The six-speed G50/31 manual gearbox with a short shifter used on the Carrera RS had modified gear ratios for the first three gears. The larger 322 mm cross drilled and ventilated discs brakes front and aft with four piston calipers were shared with the 911 Turbo and limited-slip differential was included as standard equipment. The exterior is easily distinguishable from a normal Carrera by a large fixed rear wing, small front flaps, and three-piece 18-inch (457 mm) aluminum wheels. The headlight washers were deleted for weightsaving reasons. A seam-welded body shell with an aluminum bonnet supported with a single strut was used along with thinner glass. On the interior, the rear seats were removed, and special racing seats along with spartan door cards were installed. Sound proofing was also reduced to a minimum. The suspension system used Bilstein dampers and the ride height was lowered for improved handling. Adjustable front and rear antiroll bars and an under-bonnet strut brace further increased handling. The final weight of the car was 1,280 kg (2,822 lb).
