125-200cc Front suspension ( fork ) setup

I tried to dial my bike in this week.
New 2013 wr 125
I got the rear set as the specs in the suspension thread. (Little less preload and bingo correct specs)
Now the front is a different animal.

Bike sag is 30 mm and rider sag is 40 mm. Me on or off the bike just makes a difference off 10 mm.
My weight varies between 155 and 158 pounds (70-72 kg).
Following the specs I need 75 mm rider sag at the front
The extra sag at the front is really welcome as I am a short guy and can't get my feet on the ground.

Maybe if I have to do the costs, it is better to have the bike completely lowered with the correct springs in the fork. At the moment I run the bike with the fork +1cm in the triple clamps but have still loose front wheel traction in tight slow twists.
What do you think changing the front springs (which ones) or a complete suspension modification?
Money is a little tight at the moment, but good suspension setup is important for me.
Al suggestions welcome.
