The 911 GT3 RS (991.2) is the wider, more track-focused GT3: the naturally aspirated 4.0-liter revving to 9,000 rpm, PDK-only, in a much wider body with a fixed carbon-fiber rear wing for downforce.

The story is construction as much as pace — a magnesium roof plus a carbon-fiber hood and front fenders. The Weissach package (carbon and titanium bits, optional magnesium wheels) was offered to shave more.
