Swaybar and springs on 35is?

hello all, i am still feel some roll in the 35is and i am thinking about lowering it and adding swaybars to eliminate the feeling, but i have the adaptive suspension, does changing springs and swaybar affect the suspension or any electronic stuff? e.g. warning lights etc?

also, i am leaning towards H&R for swaybars, any comments / suggestions for springs?

and to those who changed springs.. what do you feel about the ride comfort? better, worsen, bumpy, smooth or the same?

H&R antiroll bars are great and you should adjust the rear in the softest position.
I recently installed the AC Schnitzer springs on adaptive suspension as well, see post #16 here

No lights of course and no electronic interference.

Garage List
Have the H&R springs and love them, they dropped the car a bit, but not too much and while the ride got a bit harder, it was just enough to notice, but not enough to bother the wife - however they are great when you push a bit, took out the excess rebound and a lot of compliancy to the suspension. The car is MUCH better on the corners and much more stabile at high (130 + mph) speeds. I would buy them again in a heartbeat. Getting ready to order the matching sway bars to finish the setup.

Had no issues wight the install, nothing needed to be reset, no errors, and no issues from the dealer (they actually liked them)
