This weekend I installed a set of Eibach sway bars. I installed them with the front setting on the soft setting (only 2 settings up front) and the middle setting in the rear (3 settings in rear). Today I took the Z for my first test drive with them. I drove through wine country rolling hills with various sweepers followed by a coastal mountian range road that has some tighter stuff. So here are my driving impressions of the eibach sways.
1) To really test them I need a race track because I was going really quick through the corners without even stressing the Z. Double the posted corner speed limit seemed pretty easy. I did not want to push it more than that.
2) They fixed a problem that I did not even know I had. I always felt that the Z was stable and cornered really flat with minimum body roll to begin with. After taking the drive I now realize what flat is.
3) I either stumbled onto the correct setting from the beggining of my install or I will not find those front/rear bias charateristics until I hit the track because turn in was nice, direct, and the car went right where I pointed it. I had VDC ON but the traction light never came on during the corners (I can't say the same for corner exit and straights).
4) I like them!!
P.S. I posted this in the general thread but wanted to post it here as well so that the review can be searched in the future.
