Strange Suspension Noise Only When Wet
Hey y'all,
Hoping someone can give me some ideas on where to investigate a strange suspension noise that seems to only appear at low speeds when the car is wet (ie, been driving in the rain). Noise will present over low speed bumps and also low speed turning. No other obvious symptoms, car drives fine and feels solid otherwise. Tire wear is normal, no strange vibrations or shaking...just this weird noise. The noise is a groan/click coming from the front end. Suspension is modified: Bilstein B8 w/Supreme Power Lowering Perches M3 bits Adjustable sway bar links My gut says it's something to do with the Supreme Power perches (did not install rubber damper on top of springs) or perhaps the washer stack on top of the strut was installed wrong, but wanted to see if anyone had any similar experiences before I tear it all down and make guesses on what will fix it.

Make sure endlinks adjusted so no preload at static ride height and try greasing sway bar bushings as they dry and grab alot. You could try to spray teflon spray on springs see if changes sound at all If does get thrust sheets or torrington bearings so spring can rotate on compression.

Well, I pulled the struts off this weekend and replaced the Supreme Power perches with factory perches, I couldn't definitively locate the source of the noise, but it's gone now. Could have been something installed wrong/loose or may have been caused by the lowering perches. Figured I'd update the thread in case someone has a similar issue in the future.
