Awesome, funny to see the see of jap cars replaced by BMW's. Where can you read up on the specs of the cars?? (after number 8, looks like a fairly stock non M3 E46)
The orange and the white M3 e92 have a GPower kit, and i think also the Gulf one have. For the Orange you can search andrewM3power on youtube and watch this thread on BMWPassion.it M3 E92 Il motorsport passion team presenta... The Gulf e92 is Ettore Carello on Facebook, the greem M3 is Alberto Cona, the Wankel MX5 is Filippo Pirini, you can also search Enrico Sartori, Amerigo Monteverde, Federico Sceriffo (team Orange), Diego Quaranta. The best M3e92 for me is this It's an original BMW M3 GT4, with GPower and wisefab or similar kit, check Francesco Conti on King of Europe 2013 ,
