A few of us on Tyresmoke are going to book up a day at Palmer Sport. If you haven't done it then I can thoroughly recommend it.
It's a full day ragging all the cars as fast as possible with encouragement from the instructors to push harder

It's about £650 which to my mind compares well against a normal trackday in your own car.
We're looking to book soon so if you're definitely interested (obviously it will depend on dates) then please post below.
Cheers
