Sway bars are loud...I never heard anything like that. We have sway bars from the factory, the aftermarket ones are just more beefer and adjustable for stiffness. I dont see how they can make noise unless they were installed wrong.

IMO, the car handles alot better than stock. Its not a slot car, but it takes corners well for a 3500lb sedan. It does not seem to have as much body roll since installing the sways. I am rolling on 235/45/18 Potenza RE050A's with Z front and unrevised coupe rear springs on my oem sport shocks/struts. Stillen sways are set to medium/medium for now.

 

Well, maybe if i get my tires sold i will look into these.
