IMSA released two separate technical bulletins regarding the Balance of Performance for the six-hour race. The first one was released on May 23, 2019, for the GT Le Mans (GTLM) class. This was done to allow IMSA teams who were preparing for the24 Hours of Le Mans in three weeks time, notablyCorvette Racing andChip Ganassi Racing, to have the beforehand knowledge of the Balance of Performance for the race so they could prepare better. In this bulletin, theBMW M8 GTE received a 12 horsepower increase, as well as a six liter increase in fuel capacity and turbo boost increase.[4][5] The second technical bulletin was released on June 19, 2019, which regarded the Balance of Performance for the Daytona Prototype International (DPi) and GT Daytona (GTD) classes. In DPi, after winning the previous two events,Team Penske's Acura ARX-05 was given a 15-kilogram weight increase, giving it the same weight as theNissan DPi. TheCadillac DPi-V.R was given a 1-liter reduction in fuel capacity. In GT Daytona, despite no McLarens participating in the 6 Hour event, the McLaren 720S was given a power increase of 15 horsepower and made 25 kilograms lighter, in addition to a 12-liter fuel capacity increase. These adjustments made the McLaren 720S the lightest car in the class, as well as having the largest fuel capacity.[6][7]
