The 911 GT3 RS 4.0 is the final evolution of the 997 and features a 4.0 litre engine. The engine itself uses the crankshaft from the RSR with increased stroke dimensions (from 76.4mm to 80.4mm). This change has increased the power to 368 kW (500 PS; 493 hp) at 8250 rpm and 460 N.m (339 lbf.ft) of torque at 5750 rpm. Chassis development has been influenced by the GT2 RS and uses bits from other RS 911s. Front dive planes give additional downforce up front. The car weighs in at 1,370 kilograms (3,000 lb), giving it a power-to-weight ratio of 365 bhp per ton. Only 600 cars will be built. Performance is a 3.9 second 0-100 kilometres per hour (62 mph) time and a top speed of 193 miles per hour (311 km/h). Calvendo Flipart are poster books, i.e. "books to hang on your wall": Each Flipart contains at least 14 individual pages, featuring pictures and text, and is spiral bound, just like a wall calendar. Flipart poster books are less complicated than posters simply because no frame is needed and also offer more variety since simply turning a page means another image will be displayed. Easy. Or, as we like to call it, Flipart!
