UPDATE: Rain Halts the Racing
The rain intensified around three a.m. as the temperature continued to fall.
Max Angelelli finally lost the led, not due to the rotten weather but due to a tiny pit lane infraction: His fueler jumped over the wall and inserted the fuel hose a few seconds before the fire-extinguisher man got over the wall. An IMSA safety official saw the infraction and called for a drive-through penalty.

Max Angelelli was leading when a pit-crew penalty cost him one position. Chris Jasurek/Epoch Times
