Those first three spins were from my "out lap" in the first session. OK, the first two were probably caused by getting on the throttle too hard, but the third one (exiting the fishhook) was relatively unprovoked. After returning to the pits, I found my tyre pressures were down at around 36psi, and increased them to 40psi. I had far fewer problems after that. I have lots of camber on the rears (about 2 degrees was the most I could get with the stock set-up) and combined with low pressures on a wet track, seems to create very little grip especially on left-hand corners (due to the orientation of the tread pattern on the driver's side). In the dry, I have absolutely no complaints about Adrenalins.
Would I buy Adrenalins again? Yes. They are excellent in the dry, good in the wet with a normal wheel alignment (our Volvo has Adrenalins too - no problems with wet grip), reasonably cheap if you shop around, and being Australian made (most sizes) I much prefer to keep a bit more of my money in this country.
I used to run Adrenalins in the 32 (drift car), and I'd say they had fairly decent grip in the wet.
Don't mean to be rude (I have only owned my NB for less then a week now, haven't really pushed as hard as you have) but it looks like all your spin outs where due to driver error - wrong racing line (tyres are out in a wet line) and to need to be a little smoother on the turn in (avoid the ripple strip)!
And 40psi is wayyyy to much for the wet, I run 36/38 (dry) and 32/34(wet) on a 1300kg skyline with 8/6kg spring rates!
Try run around 32psi all over and see if there's an improvement.
