In this Bulletin, the BMW M8 GTE received a reduction of turbo boost, as well as a 4-liter fuel capacity reduction. The second technical bulletin was released on June 21, 2018, which regarded the Balance of Performance in the Prototype (P) and GT Daytona (GTD) classes for the event.^[4] In P, The Acura ARX-05 and Cadillac DPi-V.R received fuel capacity reductions of 2 liters. In GTD, Acura NSX GT3 received a 10 kilogram weight increase while the BMW M6 GT3 received a fuel capacity of reduction 2 liters.

Saturday afternoon's 65-minute qualifying session was divided into three groups.^[14] All three categories had 15-minute individual sessions, and regulations stipulated teams to nominate a single driver to qualify their cars.
