Its been about two weeks since I installed my rear 19mm Promini swaybar. I have lately noticed a clunk sound comming from the boot area when I back out of my driveway(there is a little curb sorta thingy) and when the weight of my car shifts quickly(like at an autocross). Has anyone else noticed this or had a simular problem? Should I get it checked out at the dealer or will they void my warranty with a aftermarket swaybar?

 

Check your subframe bolts for tightness. They back out unless you
tighten them down well. I used blue thread-lock when I did my Alta
swaybar install just to be safe.

 

I'd also check any bushings to make sure they're installed properly.
