Morale was high. Spirits were light. We had effectively torn the car completely apart and buttoned it back up in two weeks, and we were about to start the ChumpCar RVA Graphics 14 Hours of Daytona this past weekend.

Been there done that except it involved a ten hour ride home so we scavenged the parts stores with in a hundred mile radius for head gasket and got good at changing them every three or four hours. Oh the fun of endurance racing.

Any time! And if it helps, we run 2 degrees of negative camber, too. More didn't seem to help tire temps at all–these don't have the grip of race slicks to take advantage of it.
