Agreed! I wouldn't say that these trims are a cause for much concern just yet. Other Hyper Coasters from Mack Rides, such as DC Rivals in Australia and Hyper Coaster in Turkey, also have trims which don't seem to have much of an effect on the pacing of the ride. It's also been speculated that these trims are installed in case the train is travelling too fast through the layout. I think that's what we could be seeing here.
