Need help on 125 SX Monoshock spring.

Hi all,
Need some help here.
I had managed to broke the bottom out bushing on the shock valve.
Not by riding over limit, only ride on the street and fire road.. but being overweight
, the bumper died within a month..
I weight 95 kgs, thus what spring rate should I use. any recommendation,
especially from Malaysian is much appreciated (as availability of the item is rather useful).
