This is based on the proposed changes that had been put up on the Snetterton redevelopment site....
Unfortunately since starting about 3 months ago, these have changed (see http://www.motorsportvision.co.uk/resources/sn_buspark/Circuitchanges.asp#1) in layout, having changed the infield section layout and completely dropping the hairpin and loop section that was supposed to replace Russells chicane. This is the reason for this being classified as a fantasy track rather than real world.
There are two layouts included, the full 5.3 km GT circuit and the 4.06 km national circuit.

Things that are not done...
