I used the Dif-E-Yo .010 Shims. One on each Bearing Post with a Luftverk Bearing Blank when I set the Deeper State up for Fixed last Month.
Mr. Adamantiumpops above this post! Runs shims and bearing blank in a deep state. Fixed Axle February-WEEK 1 - #75 by adamantiumpops
I assume it would also work with shims and a Half Spec Bearing. But the Greased standard bearing has worked well for me.
