I put mine at stiffest setting on both front and back. The car is still very responsive on quick side to side or "S" turns (that's the whole point of stiffer sway bars) , and I even tried to see if it will over-rotate if I pushed it, and I could.. the back end felt it was coming around and the VDC kicked in... so understeer at those settings did not appear to be a problem. I went home and did some Math (virtue of being an engineer) and here is what I come up with - very simple, but sorry if I bore you!

Stock Sway Bar settings: Front @ 416 lbs/Sq Inch, Rear @ 374 lbs/Sq Inch - Ratio Front to Back = 416/374 = 1.1123 or 11.23% Front being stiffer than Rear (Understeer Baseline)

Eibach Sway Bar Settings (Stiffest): Front @ 900 lbs/ Sq Inch, Rear @ 860 lbs/Sq Inch - Ratio Front to Back = 900/860 = 1.0465 or 4.65% Front being stiffer than Rear (Less Understeer than Stock Sway Bars by 6.58%)

So in effect, at the stiffest settings on the EIBACH's, I dialed out 6.58% less stiffness in the Front or that much less under-steer... AND now I also dialed out the little plowing as well... so she is solid but still turns on a dime... not a bad deal...
