The tubes with the dual disc setup do fit the triple trees, both sets of tubes are 35mm. The pair of calipers I got to use with the dual disc do not work with that wheel so you would need to find dual calipers from a different model GS550.
I MIGHT have some paperwork showing the model the wheel or the calipers came from, but that is a big "MIGHT".
If you are really interested I will look for it.
