ToyBox Speedway Unlocks List required

I saw a note on the DisneyInfinityFans PSN group about unlocking Sugar Rush stands or something to that effect.
Since I couldn't find the item described in the ToyBoxStore, I think I need a list of Toy Box Items specifically unlockable via this playset.

Does anyone know where I can find this list?

I thought the item in question might be useful for my racetrack ToyBox:

The gap in the stadium is the Sugar Rush section of the race track.
That's where I was planning to put the SR stands if they are suitable.

If there are other themed stands, I would want to use them as well.
I don't imagine there are enough variations to fit all the sections, but there should be at least three more I can use.
The icy section is the Arendelle section of the racetrack and that is definitely one of the racetracks.
There is also a San Fransokyo and Halloween Town section (not pictured) which are also racetracks.

There is a complete list of speedway unlockables over at infinityguru. You can find it here.

Only one set of Themed Stands?
That's a pity.
I was hoping there would be others.

Well, at least the list confirmed my only remaining task is to unlock the Sugar Rush Stands.

yeah, only one set of stands and don't get too excited as they cannot have any logic connected to them

They can't?

I was experimenting with the Regular Stands and 4 options were given for logic connections (Soft Cheering, Cheering, Loud Cheering, Booing).
I couldn't hear the sound though when I tested it, so I wondered if disabling the music also disabled the cheering sound effect too.

[Sheriff Woody]

nope, unfortunately they can't. very disappointing. disabling music does not disable the crowd cheering. we need to disable background music for youtube recordings and the crowd can still be heard ...
