So here it is. I run the same track every week (high bite clay). My set up is dialed (or was). Here is the issue. When the track is freshly watered the car is dialed.

The problem is if my heat is later and the track starts drying out the rear end is super loose. Not just a little loose but a whole different car.

Is there something minor that can get changed based on the track conditions that can quickly go back and forth between?

Hopefully this makes sense.
