Porsche also paid a good deal of attention to realsiing the best possible power-to-weight ratio, and as output would be remaining unchanged at 381bhp, a variety of special parts had to be installed. These included a plastic rear window and single mass flywheel, carbonfibre being used for the front lid, rear spoiler, engine cover and wing mirrors. All this equated to a 50kg weight saving over the standard MkII GT3. The interior was equipped in much the same fashion as any Club Sport; competition Recaro bucket seats in flame-retardant fabric, six-point harnesses, a roll-cage and fire extinguishing system. Alcantara was used to trim the steering wheel rim, the stitching of which (along with the seatbelts) matched the choice of either blue or red exterior graphics. Uniquely, all RS variants came with a series of three vents carved from the nose to improve cooling and a special close-ratio six-speed gearbox.
