Yep I got F-sport springs. hmm...should've known before wasting $200.

 

will you feel a difference if you are slammed on coils before the sway?

 

I put the F sport sway set and really didn't notice a difference. Because I drive like the old lady I am, I was told that eventually I would feel the difference if I were to drive where it WOULD make a difference.

I then put on the F sport springs/shocks combo.

I noticed a difference in ride right away.

Then when I had to do an emergency reaction to a large plastic thing flying out of a truck toward me, the car maneuvered in a quick emergency without a hitch. I know what the difference is NOW. And I truly appreciate my purchase.

 

people have to remember these are "SWAY" bars. They only can be felt when swaying to either side. You can't tell/feel you have them while driving straight. Taking a turn at a higher speed or quickly is when the Sway bars will be felt.

 

For real. And they DO work.

 

To definitively feel a difference, you really have to know how the car handles on twisty roads near the limit without sways and compare that to how the car drives near the limit with sways. Problem is, "near the limit" is almost certainly well above the legal speed limit.

The sway bars made an enormous difference for handling at the limit for the IS350. It's night and day.

 

ahh ok...So I have to drive like a mad men to feel the difference.

 

Yes and ahh ok, the night and day road test results are a very scientific conclusion.

My IS350 on Eibach 350's (same as F-sport springs), OEM sport pkg shocks and 19" T1R tires has flat cornering and far more cornering grip than I can ever use safely on public roads. I never get close to handling limits on public roads.
