In the first race for IMSA's new GTD Pro class, which replaces the GTLM division in which RLL fielded an M8 GTE last year, the works BMW team struggled for pace as the M4 GT3 made its US competition bow.
It sat at the bottom of the fastest lap times, the M4's in-race best of 1m46.897s set by Jesse Krohn aboard the #25 entry almost two seconds off the best GTD Pro lap of 1m45.087s from Laurens Vanthoor's KCMG Porsche. It was also slower than the best efforts posted by many silver-graded drivers in the pro-am GTD class.
