Le Mans: Changeable conditions

Just had a race at Le Mans with GTE/DPi. The conditions were unpredictable & changeable; race started dry, then wet, & dry again. All brilliantly done, except for one thing; the AI were blisteringly quick, on dry tires, in very wet/soaked conditions. I was playing at 113, aggression low, and was in the top 3, until the rain came. Then all of the AI overtook me, in the wet on dry tires; they were so quick however, it was as if they were on wets. They were also braking extremely late; too late for these conditions & appeared totally unaffected by aquaplaning. The racing at Le Mans in stable conditions, is fantastIc; but when it’s unpredictable, the AI becomes very inconsistent. Maybe this should be looked.
