Just a follow up, pulled the spacers out and cut them to 50mm.
Checked fork travel and is 200mm.
Reinstalled and now have 30mm static sag and 60mm rider sag.
To sum up - Factory spring 440mm and 195mm spacer, Ohlins 08716-60 spring 590mm and have used a 50mm spacer.
Mind you I am a fat b@stard at 130 kg.
