Looks a fun day !
The 888's are great tyres the uneducated people at track days always say 'oh your braving runing with them on' but in reality the regulars all have them wet or dry. You actually learn the cars characteristics much quicker in the wet with them on due to the hightened feel they give.
drivers like that exige driver do my box in, they pull over for you and keep the boot down whats the point. You only catch them again at the next set of corners. I was stuck behind an S2000 for 3 laps and he surprisingly never pulled away on the straights, neck and neck all the way which resulted in me getting very fed up and coming in.
Steve, what camera and mount are you using as im looking into getting one ???
