Maybe the cornering speed is in the game too?
My car might not getting fast enough to have trouble with the front axle.
This year I have a go with a new cam that might boost the engine power.
Maybe this year trouble starts with the brake system.
Always you limb in racing speed new problems you are facing.

The residual pressure valve helps, and you can do as I used to do and fit a
stronger one if it's not enough, but your pads will drag a little. I think
the biggest advantage of the uprated axle is the ability to shim the
bearings for a precise preload and then torque the nut tight. I get a very
free=spinning wheel that doesn't wobble and doesn't knock the pads back.
Everything helps, but all these things are compromises.
