McLaren MP4-12C GT3 (2011) track testing begins

McLaren has begun testing its latest track weapon, the MP4-12C GT3 ahead of the 2012 FIA GT3 season.  How different is the MP4-12C GT3 from the roadgoing edition? The MP4-12C GT3 is based on the standard machine but modified for FIA GT racing by McLaren GT - a joint venture between McLaren Automotive and CRS Racing, a UK-based team currently competing in FIA GT with Ferrari F430s.  Externally you'll notice the race-spec fixed rear wing, undertray diffuser, front splitter, louvres and vents. Underneath there's a new suspension system, ditching the road car's linked suspension for FIA-compliant conventional dampers and anti-roll bars. Akebono is supplying race-specific brake components, and Bosch Motorsport has installed its ABS system. The car sits 100mm wider on its new suspension and has suitably flared bodywork as a result.  It's still the McLaren's bespoke 3.8-litre twin-turbo V8 engine, tuned for racing.
