Ideal setup still relevant wet

I’ve used the ideal setup button which has set the correct ride, suspension and wing levels, but is that taking into account the live weather? 

I take it the answer should be yes, but just checking as to whether I need to add the wet weather ride height adjustments, or at least be aware next time I race this circuit without rain to go much lower with the height settings?

Yep! Ideal set up varies from wet to dry as required.
