Audi can build a clutch that lasts for 300km.The problem is Renault,Peugeot or Lancia can also do that.SO Audi tries to make their clutch smaller and lighter.You know what I want to say... Watch these videos. . Kubica and Alonso(the drivers in the videos)were excellent karting drivers.If there's something karting teaches you,it's to be very agressive at all time.And guess what?you have to be even more agressive in wet conditions.And that's what they did. I don't think I need to tell you that the fastest drivers in the world all began their careers by driving karts. Theory and practice are completly different things.
