i installed the perrin evo x sway bar, but when my car goes over any bump i hear a weird noise almost like a shifting/rubbing.....

can this be because i have it to tight or the higest hard setting.

any info would be great...

 

i had that noise when my bolt is losing...once i tighten it, the noise is gone.

 

put blue loctite on your endlink nuts and torque them down. you won't have this problem again.

 

Since it sounds like this question may of been answered... I want to slightly derail the thread... is there any difference between the Perrin sway bar and the cusco sway bar?

 

where you getting the Perrin sway bar at?

 

Perrin is adjustable, cusco isn't from what I saw.

other than that, look at the effective rates on the bars to determine how aggressive you'd like to go. Perrin has good rates.
