Rear end feels 'floaty'

[Slaninar]

2.2 bar is 32psi, that's way off for the rear and would actually add to a floaty feeling???

Depending how you ride and warm the tyres up. I'd try both 2.2 and higher 2.5 bars. See how it feels. Lower pressure in tyres makes suspension work a bit less hard. Up to a point.

I'm no expert, so correct me if I'm wrong and take it all with a grain of salt. But I'd start from good tyres, only then change suspension.
