Have you tried your setup without the 8mm mod on the rear? If so, what did you experience?

For me personally Probably would go with lower oil weight up front, maybe 27.5 . For the rear spring, is that Yellow rear stock or Yellow fronts on the rear? I probaby would go up on spring to the Fronts personally.

As for the inner rear a-arm position for the shock, have you tried the outside position? Same question on the upper shock mount position (but say the middle position).
