Tudor uses ACO regulations as a basis, but IMSA puts their own spin on things and makes concessions as they see fit. ACO doesn't let brands get away with as much sh*t, as IMSA does.
Even back when BMW ran the M3 in ALMS. They were allowed to run a larger air restrictor. They also allowed the M3's to mount the rear wing higher on the decklid than the competition, as well as running a larger front splitter/diffuser than that allowed by ACO regulations.
This difference in rules came into play last time BMW showed up at 24hr Le Mans. Running a non-stock double wishbone suspension, in which they were given a conscession for in ALMS. But ACO made them change it just prior to the 24hr race. It pissed BMW off and they havn't been back since.
