= Entry list =

Eighteen cars were officially entered for the Oak Tree Grand Prix, with most of the entries being in the Grand Touring Daytona (GTD) category. GTLM was represented by eight entries from four different brands. In the list of GTD entrants, ten GT-specification vehicles were represented by six different manufacturers.{{Cite web |last=DiZinno |first=Tony |date=12 August 2015 |title=No Major Changes on VIR TUSC, CTSC Entry Lists |url=https://sportscar365.com/imsa/impc/no-major-changes-on-vir-tusc-ctsc-entry-lists/ |access-date=5 November 2024 |website=Sportscar365.com |publisher=John Dagys Media, LLC}} With the absence of the Prototype (P) and Prototype Challenge (PC) classes from the field, only two racing classes were represented in Virginia International Raceway.

Qualifying

Saturday afternoon's 40-minute two-group qualifying session gave 15-minute sessions to all categories. Cars in GTD were sent out first before those grouped in GTLM had a separate identically timed session. Regulations stipulated teams to nominate one qualifying driver, with the fastest laps determining each class starting order. IMSA would arrange the grid to put all GTLMs ahead of the GTD cars.{{Cite web |last=Dagys |first=John |date=20 August 2015 |title=Continental Tire Keys to the Race: VIR |url=https://sportscar365.com/imsa/impc/continental-tire-keys-to-the-race-vir/ |access-date=5 November 2024 |website=Sportscar365.com |publisher=John Dagys Media, LLC}}
