I've been dragging my feet on posting anything for the last 30 minutes or so, waiting for something significant to happen at the top of any of the classes. Really, not a whole lot has changed since my last post about 90 minutes ago, with the exception of the #4 Corvette hitting trouble and dropping out of the lead battle in GTLM. Good news: that does still mean that all the classes are still up for grabs, with at least two cars on the lead lap in every class. In particular, GTD has four or five cars on the lead lap (it's hard to tell from the IMSA.com timing and scoring page, as it refreshes every 30 seconds or so).
We are potentially in for a great battle, that comes down to the last 10 minutes in every class. Can't ask for a whole lot more, can you?
