that sounds awesome - but isnt 55 quid expensive for only 30 mins of racing.
I organised a simialr thing here in slough and it would have come to 35 quid for 10 people or more for an hours race.
Not knocking it all but just thought I would share my tupence worth.
Nothing beats go kartin in Spain as we destroyed about 4 cars in the first day and then went back the next day and destroyed some more

they didnt even care
