I've been thinking about adding cusco's front and rear antiroll bar. Anyone has them on their car? Any brand? Is the car alot bouncier and stiffer? Do you regret having them on the car now? Please let me know your experience with them. Thanks

 

Why do you want them? Track Road racing, autocross, or just street?

 

All anti-roll bars will make the car feel bouncier and stiffer. Just be careful not to go too stiff if for street use (particularly with the rear bar). You can detract from your cars handling substantially by doing so.

Talk to others. Find out how their setups perform on wet roads in particular. (In the wet cars with too stiff a setup can lose the rear end on the slightest irregularity or ridge in the road surface.)
