In 2003 Porsche launched the GT3 RS in order to homologate the GT3 RSR for racing. While you could drive the 996.1 and 996.2 GT3 on the road, the GT3 RS was a more uncompromising track-ready 911 that was tough as a road car.
GT3 RS horsepower remained the same as the GT3 but there was a real difference in performance from other changes. Wider tires were fitted with a revised suspension for track use, and a large rear spoiler was fitted to help increase downforce. Weight was reduced by removing interior sound deadening, air conditioning, rear seats, and adding a Perspex rear window. The diet meant the GT3 RS tipped the scales at just under 3,000 pounds (110 pounds lighter than the GT3). All GT3 RS cars were also fitted with a full roll cage. Reduced mass was advantageous to the car’s performance, since power and torque remained identical to the 996.2 GT3.
The emphasis for Porsche was on achieving the best possible power-to-weight ratio and with a figure of 4.86 kg/kW has resulted it was 4% better than GT3. The GT3 RS power is transmitted via a close-ratio six-speed gearbox. Between the engine and the gearbox, the “RS” has a single-mass flywheel with a lower rotating mass than the double-mass version. Performance improved with 0–60 mph time of 4.2 seconds and top speed of 190 mph. The biggest differences came on track however, with the GT3 RS being a purer race car and perfect circuit car.
As for the 996 GT3 RS, its place in history is already secured. Rarity, status and ability have already led to soaring prices. It’s not unusual to find examples on sale for far more than a brand-new 991 GT3 RS.
