2014 Triple R Ohlins Nix30 Front Shock Springs

I need some help guys, i am at the point now to replace the front springs, not ready to send them to a shop yet...The ohlins suspension on the R is made for the track, but them days are over for me now....i find the front shock to harsh no matter how i adjust the pre and comp i just changed the oil 5w... smooth road its ok, any bumps spoil the ride... soften it up and it turns into a pongo stick... the rear i am ok with ...has anyone else replaced the springs in these forks to a lighter one, i just need the part #. i think these stock springs are 9.5 N/mm.... sag 37mm....pre 7 ..comp...20....reb 14
