Started this race the other day. Running the jag tuned to 650hp. 7.5hrs in, 2 laps ahead, rain the whole time, running intermediates. 13 lap stints. Low 4min laps, besides pit out which are in the 5:20 range. The headlight glare off the spray is awesome, but definitely makes passing much trickier and you can definitely become disoriented easily. I would definitely use a car with light toggle for passing purposes, to reduce glare. I do hope the rain stays though as it makes stints much longer, which helps the time go by quicker.
