Hey guys I am a 3GS owner trying to get some answers on a coilover issue and I know you IS guys do a lot more mods than the 3 GS guys. I have noticed that over the last 3 weeks I have been getting a mild clunking noise when I hit minor cracks in the road. The noise isnt a metal on metal noise. It seems more like a rubber on metal clunking noise. I called Tein USA today and they said to check that the shock towers are tight and to check the bushings and bump stops. I dont hear anything with oscillations in the road or even large cracks. Its usually at speeds below 45 and on small cracks or imperfections in the road. I was wondering if you guys had any ideas.

I am taking my car into the shop that did the install this monday so I am assuming they will be able to sort it out. I hope its just something loose because the the coilovers barely have 30-35k on them. I had a full suspension on my Infiniti G35 and pushed it very every hard for 130K with no issues.

do you guys check the bolt that tight the strut rod that where you adjust the damper? It happen to my flex coil from my previous IS300 when i heard the clunk noise and found out the bolt that tight the strut rod was loose.

Coilover noises are almost always a loose component, check that EVERYTHING is tight.
