Clunking sound from rear suspension?

Within the last few weeks I have noticed a subtle clunking sound from the rear when travelling over bumps.

I have PSS9's set to GT2 ride height specs. Seth and I believe that it may be the plastic bushings in the factory strut mounts beginning to fail. We checked all the nuts for tightness and everything appreared to be okay yet the sound seems to be getting progressively more noticable.

I only have 6-7K miles on this suspension so it seems a bit soon for this to be happening but I was curious if any of you have noticed and what you have done to correct the situation?

Loose swaybar. Pretty common. Dealer tightened mine up last month.

If not the sway bar, maybe your hitting the bump stops??? GT2 spec is pretty low for a PSS9 set up...

Brit,

GT2 spec?? I thought using PSS-9's at GT2 spec meant you were riding on the bump stops? Any high speed stability issues that others have experienced with GT2 spec on PSS-9's?
