I was looking at this on another thread, so am including the info here. If you download the install manual for Ohlins Road & Track, which has independent height adjustment and spring load, and which can be used on ether 986 or 987, you can see the differences in the heights by looking at the spring load setting and height adjustment differences between 986/987

986 front - 15 mm of spring load and 80 mm between lower spring collar and height adjustment collar
987 front - 2 mm of spring load and 59 mm between lower spring collar and height adjustment collar
986 rear - 15 mm of spring load and 130 mm between lower spring collar and height adjustment collar
987 rear - 2 mm of spring load and 105 mm between lower spring collar and height adjustment collar

The PSS9 doesn't have the lower independent height adjuster and so all the height has to be done by moving the lower spring collar and it might take the strut piston out of the sweet spot in the middle and to where it is topping or bottoming out.

If that can be solved, MCS will sell the sleeves to adapt the strut bottoms.
