Ive been chasing down a clunk with $$$ for a year. Put on Steeda camber plates, gt500 a arms, bmr sway/links, koni struts, etc still clunks over bumps and makes my car sound like a pile. I'm gonna try lubing the sway bushings and tightening the endlinks, if that doesnt work im going to try replacing my koni struts even though they have under 20k on them.
