There is now a small preview of this meeting on the TSR site - some points I picked up from it which are worth highlighting;
a) They are expecting around 50 F1 Stock Cars
b) There will be a minimum of 6 F1 races
c) The first race will be a white & yellow race and this will take place at 6.15pm (might be worth getting advance queue jumper ticket if u think u might be lateish as i bet there will be a queue to get in then!)
d) One of the heats will be for the driver of the year - closed grid 12 laps, £50 for the leader of each lap and £500 for the winner!
e) and although it is not on TSR site, the weather forecasts are all looking good in the east for Saturday!!!
Looks like being good!
