+1 to all that,
also worth checking oil level, and dont stay out too long, make sure you do a cool down lap after youve hooned it otherwise you will cook the brakes,
ive used moris before for insurance but as Ekona said the figures are about right, also be aware that there is never any blame on a trackday, imo it isnt you driving like a tit you have to worry about, its others, if someone else hits you then no blame is put on them, its up to you to sort it.... (ive always took insurance before but will consider not doing next time)
oh, and make sure you have fun cc is great
