Sorry to dredge up an old thread, I too have looked for a 90NM spring for my Ohlins shock after being told.by OTR that the hardest spring they can offer is for a 115kg rider.

The spring that came on my shock was 80nm and i assumed that it was suitable for 115kg rider. However i cannot get the rider sag anywhere near. The 40-50mm recomended by ohlins. Im at almost double that.
My weight with gear is around 120kg.
It now makes me wander if they have sent me the incorrect spring.
