Well, Sahlens was 2 GT full time cars. Now they're 2 full time DP. APR has run out of support to run Barber which is their home track because APR's shop is located in Opelika, AL. That's +2 DP and -3 GT right there for this week. Also, Brumos has no plans of fielding its 59 car after Road Atlanta. Next year, even more GAGT teams are leaving their classes. Marsh Racing is going to field a Corvette DP next season. The ESM Ferrari with Mike Hedlund and Johannes Van Overbeck is running the NAEC only along with COTA, Laguna Seca, and possibly 1 or 2 more races. Plus, Mike Shank went back to a 2 car DP team. That's another DP up from last year. BTE sport has been racing as has Doran, but both are NAEC plus COTA and maybe Laguna Seca from what I understand. Krohn in DP was a 1-off at COTA. Next year will be the true measuring stick as to how many GT teams stay. I have no clue what Stevenson will do. That's the team that's getting left out of the merger because of a pro-am driver requirement for GTD. I think they end up going to a Corvette DP as well, but that's just my own speculation.
