Thanks for the input everyone!
Sure helps to know what everyone's experiences are.
I did some hunting and even on Associated's site they recommend to run in with the recommended shimming. I'll give that a try.
Completed 90% of the car and the rest of the built was very very good. Parts were properly organized by build steps and the quality seemed top notch. Other than the notchy transmission - everything went together well with no fit or finishing issues whatsoever.
Read Jimmy's (fantastic) review on the BJ4WE to see the differences that AE has made to the car... many subtle changes, and the slipper certainly looks like a major improvement.
Will run in the car once I get the electronics installed and update on the notchy diffs...
