130 is fine.
5 mm difference is greater as you increase the level, so keep the last 5 in reserve in case you want to try it.
Do not go less than 125.
Suggested is 15 mm of internal preload for your 0.925 setup.
Given the rear spring you are running on the Ohlins, you might want to later try going to 10 mm of internal preload.
You are going to do serious track lapping on a regular basis.
You really do want to know how much fork and shock stroke you are using.
Zip tie your shock shaft.
When doing the front springs, when they are out, slowly fully bottom out one fork leg, put a zip tie on the fork tube so its edge is resting on the top of the dust cover lip. Then put a wrap of tape right above the zip tie.
The tape tells you the relationship between fork stroke and hard mechanical bottom out - which you do NOT want to hit !
You really don't want to see less than a 7 mm gap between the zip tie and the tape (assuming a 3 mm wide zip tie). Once you are into the last 10 mm or so of fork stroke, you're into the hydraulic cushion zone which is there as protection against hard mechanical bottoming. The hydraulic cushion zone has a tendency to keep the fork compressed when the front end forces are released, in other words behave like an uncontrolled excessive rebound device.
There are things you can do to reduce the hard front braking induced fork stroke.
Slide back on the seat.
Grip the tank as hard as you can.
Keep down low.
Do not lock elbows.
Use your gut and lower back muscles to keep you in place and NOT your arms !
Feed in the front brake, don't jump on it.
Once you master all the above, then add in beginning with some rear brake before you even touch the front, it must be before in order to be effective.
Use of the rear with hard front braking on a 919 is for chassis pitch control and nothing else but, it's not the rear braking power you are after, just the chassis reaction it gives you.
