Reducing the front sway bar from 29mm to 28mm [from t or active wreck] reduces the front understeer by ~ 1/2 of 13% or 6-7% which is feelable and especially feelable with a front strut brace.
The sway bar is in parallel with 146 # springs thus the 1/2 effect.
The first 1" +- of body roll has the sway bar compressing rubber bushings so not much happens until these 6 bushings are compressed: 1/8" x4 = 1/2" of slack...............which because of where the bar mounts results in 2" of body roll BEFORE things start working.
Replacing all rubber bushings with urethane can be jarring but half of each can work wonders.
The strut bar is directly coupled to sheet metal so no slack.
