For the most part, there's very few significant changes in the entry list this time around. Of note, the #79 JDC-Miller LMP2 is set to return to competition, alongside #18 Era Motorsport and #37 Intersport Orecas, both of which were absent from Mosport last time out. The MEC regulars from the likes of Manthey, RS1, AF Corse and others are set to return to their respective GTD classes. YRB Racing and their "Car Blanche" Aston Martin will return to the GTD category for this event.
The BoP changes for Road America have also been announced.

And this time there's a handy little table courtesy of the IMSA subreddit.
In GTP, the most noteworthy adjustment is the addition of 21 kilos of weight to the championship-leading Cadillac(s). Otherwise, it's relatively light adjustments here-and-there in the class, as well as no changes to the Valkyrie's power and weight from Watkins Glen, though it does loose out a little bit on fuel capacity and refuel rate.
In the GTD classes, the Corvette Z06 gains an additional 15 kilos of weight, making it the 2nd-heaviest GT3 car behind the 911 GT3 R, though the latter will once again be the only GT3 to run 100% power in both stages. Elsewhere, the M4 GT3 gains an additional 6 kilos, while the Aston Martin Vantage and Lamborghini Huracan both lose 15 Kilos from Mosport. Power changes among the GT3 cars seem to be relativley tame, though the Lexus GT3 sees the biggest loss at nearly 4% of Stage 1 power,
On paper, it's looking like BMW and Acura will be the ones to watch in GTP, though I'm sure AXR and Porsche Penske will do their best to be a thorn in those teams' sides. in the GT classes, it's a little bit harder to say. BMW are probably the favorited in GTD Pro, what with Paul Miller Racing currently leading the championship in that class, though the Porsches 100% power may prove useful, with Road America being more of a power track. At the same time, the McLaren of RLL might have a shot at a good result. That team has regualry shown speed this year, so I'm hoping they can finally have a good race from beginning to end this time around. As far as GTD, I'm expecting another good fight between the THOR Aston Martin, the Vasser Sullivan Lexus, and Winward Racings Mercedes.
