Circuit - If you haven't been there before, Croft is an absolutely fantastic circuit whch I much prefer to Knockhill. It is over 2 miles long, and has some great fast corners which flow into each other, including Barcroft which is taken at around 100mph

Cost - is £125, cheaper than a normal full day organised by the circuit themeselves. LOT operates as a club which you have to join, but they will do you a discount if you are from Scotland as most of the days they organise are down south. Booking info here http://www.lotus-on-track.com
Noise Limit - is 98Db static. Not as bad as it sounds. My Larini is bloody loud at full chat on drive by, but was only measured at 96 static at Croft earlier this year. If you have got a stage 2, bosh your standard zaust back on. It will be well worth it.
Format - like all Croft days it is not open pit lane, but divided into 3 groups with a 20 minute session each per hour. Don't let this put you off - I found the format works really well - think Jamie will concur. There is never any crouding on track, and the circuit is so fast and demanding 20 minutes per hour was enough for me. 20 minutes drive, 20 minutes pax, 20 minutes chill before the next drive seemed to good mix.
The plan for the weekend will probably be to head down Fri evening and have a few beers. There are plenty of nice villages and B+Bs to stay in nearby.
