All the trackdays i usually go to are with circuit club, can't be pleased more with there trackdays
-Timing is included (free of charge)
-Cars are split into groups A B C D usually 10-15 cars per group so the track isn't overloaded with cars at one time
-Lockup Garages(Use to be provided at wakefield but ithink this is no longer available since the new owners of wakefield park) - free of charge
They usually have a few guys that can show you the lines and braking points for beginners.
Prizes to the fastest guys of the day
Also their days are usually on weekends or public holidays if you intend on going book 3-4weeks in advanced because by the last 2 weeks they are usually sold out.
If you go with these guys you won't be disappointed, been around for YEARS a very well organised group.
