I think you should work with someone that knows how to set up the gears and lash if you are having issues with your diff not performing well. Also, what diff fluid and weight are you using, it can make a difference.

I'm just trying to be explicit as to why and aftermarket option is not a viable solution. To complicate things I also do Time Trials and conflicting rule sets mean I have to give up a one thing to stay legal for the other. True Coil over rears are legal for Time Trials Touring class, but relocating the spring is not legal for Street Touring autocross, not that moving the spring provides any advantage just changes the rate you need to run to have the same wheel rate. I can run 11" wheels and 315 tires for solo but only 10.5 wheel with 285 tire for Time Trials.

There is nothing wrong with my lash in my diff, it's that the engagement is too agressive and when engaged it's full on locked. I'm running the motul esther 140w90. It's as if the ramps are too steep allowing for immediate engagement under the lightest load. I've got the preload set to it's lowest but when activated it's full lockup. It's as if it's for too many plates. I have not opened the carrier to count the plates. I miss the simple clutch type used in the Z31's.
