Track is med sized outdoor loomy , bumpy in areas, moist track.
Only change made from last race was center diff. Car gained more mid& exit steering .
Also removed some droop from rear to keep it from over rotating during offpower or mild breaking tight turns .
Was able to stay more consistent thru entire race with this setup.

I tried 3 different tires (Ss gridirons, Ss crowbars ,Ss double dees)confirm it wasn't a tire thing also.
