I run wide tires 315 square -3.3 front and -2.0 rear all with a tad toe. Caster is 6. If you are not doing tire temp in the hot pit after the tire is up to temp then forget about it. Play with your tire pressures. It is the easiest and most consistent way to adjust to conditions for those of us that don't have team of folks to help us and is still a what the big teams do. Once they have temps were they want them they play with tire pressure to dial it in.
