I bring it up as I drove a friends 2005 M3 CS earlier, standard on 19's with Michelin PSS and it had no issues with full throttle in 2nd in the wet. His car obviously has more weight in rear, better wet tyres and is a much newer car, but had no slip at all. Mine just seems to spin up too easily in the wet for my liking.

Your cold pressures are too high for Track Work, hence why U suffer from excessive wheel spin ... they should be around 26 psi cold.
