Looks like the base of the seat has been redone quite a bit

The seats are definitely lower with the rows now all in line. They're also now connected at the base as one whole piece.

Also, tuned mass dampers were added to supports on both sides of the incline to the tower to help with the track sway.

That's brilliant, like a skyscraper only at the bottom. Seeing the entire wheel bogie would be ideal, because I can see the connection to the side and upstops are very different. I figured the seats would be lower (reference).
