Silverstone GP in Westfield V8 and Global GT1

Having just bought a 2 car trailer I took both my cars along to Silverstone for a great day on the GP circuit with 2 mates in their cars.. The Westy hadn't run for a while and had a great new 5L V8 engine blowing 375bhp through a rather non existent exhaust.!. My other car, the Global GT1, was great fun to drive and felt quicker but in reality was loosing lots of time on the straights with it's meagre 150bhp.. It was fun hopping between the two so I decided to do the same in this video :-)
