It was awesome!!
The first day was completely dry and I managed to pull a 1:40.444. I met some guys that run in the Spec Boxster class with POC so they gave me a few pointers.
The first two sessions of the second day were dry then the rain hit...and it hit hard. The third session it was bucketing down rain but the car handled well and we just had to adjust our braking points and driving style (ie. brake, then turn, then accelerate...no overlapping). I spun a couple of times but nothing too exciting. It continued to rain on and off for the day so you would sometimes get a dryish track for a bit...then puddles again.
The track was surprisingly good at getting rid of the water...the scariest standing water was on the front straight..each time I would hit a puddle the car would shimmy and I'd get some wheel spin...at 100mph that is a bit freaky.
The second day I also did a drivers ed with a porsche race driver from europe. He was really good and had some good tips for dry and wet driving. I was really stoked when he got in the car late on Sunday and after three laps told me he had nothing really to say...just to keep doing exactly what I am doing and just push a bit harder (he actually thought the organizers were playing a trick on him and sticking me in as a joke)...that was a real ego boost.
Thanks to everyone here for giving me more confidence to go up there. I am glad I have now driven in the rain....next time it won't even phase me.
