Here's my setup: Progress Sport lowering springs, Koni adjustables (set at 3 turns in the front, factory setting for rear), FSTB.

So here's my problem: Body roll is increasingly coming back. It's weird. It's almost like my car is again floating when taking curves at high speeds and I am again feeling as if I have less control. What it really feels like is that the springs have lost their stiffness and is causing me to float. OR, it feels like the strut bar has lost it's rigidity and is causing me to float. I mean guys, I'm floating pretty bad. I get body roll taking a normal curve (I use to take at 90mph easily) at 70mph. Any suggestions??? New springs......strut bar maybe. Thomas, aka SX7R, was thiking my struts. Could it be something besides my springs, struts, or FSTB??? I don't even know where to begin. Any suggestions or thoughts would help. I'm stumped.

 

How long ago did you install these springs? Springs, just like any other automotive part have a 'expected life'. Perhaps you have reached the end of your spring's life. This also holds true for the struts/shocks.

 

The Konis might have lost their intial bite and might have to be adjusted again.

But I noticed you don't have a RSB? Trust me, even if something "might" be wrong with your suspension(which I doubt for now), the rsb will put MUCH more load on the rear and take alot of the load OFF the front.

 

I didnt know that springs wear out after so many miles, I bought 3 sets of aftermarket springs Eibach, Intrax, and Dropzones. They all come with lifetime warranty as long as you dont modify them in any way, so does that still mean you have to replace springs? I would think only struts but not springs. This is the first time I heard of springs having with expected life. Konis come with warranty as well, so if they mess up just remove them and send them back, but if anything they are suppose to get stiffer not more soft.

Pop your hood and see if your shocks need to get readjusted again.

 

Excessive body roll is controlled by the front stabalizer bar. Being you don't have a rear aftermarket. Check the bushings to see if they have worn out giving you excess play. The front sway bar is connected to the lower control arm. There are bushings which connect the ends of the arm to the control arm and bushings that the bar itself are mounted to the car with. Other then that, your struts may need to be adjusted or perhaps have failed or are getting weak.

 

The springs have about 30K on them. The next thing I will do is probably go ahead and get a RSB and upgrade to polyurethane bushings...anybody know where the best place to get these and what kind?? Also, when you say re-adjust the struts, do you mean the settings on them????

 

Yes, you mentioned they were adjustable, make them stiffer.

 

No it's not. Springs, shocks, front and REAR swaybars all contribute to the handling of the car. As does alignment and type of bushings.

 

I have an ADDCO Rear Anti-Sway bar which I bought from
www.cattman.com

I paid $119 + $18 shipping. I believe this is a good price.
You can also buy from Greg @ CustomMaxima.com for $4 less.
