Edit. Changed pack name to part 1. Parts 2 and 3 will follow when ready.
Teams included, both drivers + talent files: Lotus Renault GP, Mercedes AMG Petronas F1 Team, Red Bull Racing, Scuderia Ferrari Marlboro, Vodafone McLaren Mercedes.
Fairly accurate, but I've took some artistic liberties in places. Probably I'll do the rest of the teams, but gonna take some time.
Unpack the zip into GSC2012 install dir (or to some temp folder and move manually). No original files are overwritten.
