Got on the cloverleaf uninterrupted this afternoon. As I approached I turned traction and stability OFF, put it in manual gate and as I entered the turn I downshifted to 4, so my RPMs were over 3K. With all that going on I didn't steer as smoothly as I would have liked: "apexed" twice, lol. I tried to get a glance at the G meter as I came around the top, but for some reason I had a bit of a challenge doing that very well too. I did snap a glance at .6 G, which isn't impressive at all; I'm pretty sure I got to at least .7 briefly because I didn't hear the tires at .6 but did hear them as I came out on top, accelerating away. And the tire sound was very low. Now the feel when I had that level of tire sound before the Eibach bar was without question a lot more movement in the back. I wouldn't describe anything I've felt at any time as "floaty", as some drivers do (but they are comparing to other high performance cars; I can't do that): but did the back end feel like it was moving in and out a bit? Yes, something like that: yet still assuredly grippy: I never felt like the rear was going to do something sudden and alarming. I would say it was planted but "playful", as Biermann likes to put it.
Now the Eibach is not only planted, it is in a smooth arc throughout the whole turn, no "in and out", nothing. Can I go faster in a turn with this? That is what I believe, but I don't know yet. I'll have to push harder next time to get the same degree of tire sound as with the OEM sway bar. I am guessing that I'll be pulling more G but not a lot more, maybe couple more tenths, when I have the tires roaring. But will the understeer be the same or less or more? Without the front sway bar, perhaps the understeer will come on more sudden like when it does. Maybe I won't push these A/S tires enough to deal with understeer; and yet I'll get at least the same G in the turn that I did with the OEM sway bar and noisy tires and a lot more feeling of control. I already know that even one time on the cloverleaf proves the Eibach keeps the rear end down and virtually motionless. Cool.
