On the front, the effect of the hex will depend on which KPI you use. KPI1 creates a NEGATIVE Scrub Radius with all hex thicknesses. KPI0 and KPI.5 create a POSITIVE Scrub Radius with all hex thicknesses.
On the rear end, you have more adjustments. With stock arm (or long arm on adjustable arm), the plastic and CNC hubs offset is at zero with 5mm hex, POSITIVE with 4mm hex, and NEGATIVE with 6mm hex. With the 3pcs Hub offset is at zero with 6mm hex, POSITIVE with 4mm and 5mm hexes, then with middle or short settings offset is NEGATIVE with all hex widths.
The following image refers to KPI1 with all hexes, and long rear arm, with 4mm hex,or 4mm or 5mm with 3pcs hub:
