Is your car lower than it was before? If so, you might want to loosen any control arms (where you have rubber bushings) and re-tighten them at the ride height you expect to be at. This is because the bushings are pre-loaded and will need to be reset to the new ride height.

 

****update***** So i took it in to another shop one recommended from the forum actually and they guys there do a lot good work on high end cars . To my luck the stupid squeaks like magic disappears exactly on the day i took it in out of all days. The mechanic put it on the lift took a quick look popped the hood and took it for a drive he was not able hear or see anything. I spoke to the guy about pre-load and he tells me i have springs and its not needed in fact he has installed the same camber as mine (spc) and never preloaded he said that is for coils. He told me he would do it if i want but he has never had to do that and never heard of a problem. Now i suspect its happening more during dry weather becasue when the humidity is up or damp like its been here past few days you cant hear the squeak. Its driving me crazy because the car rides great but its the squeak that's so annoying..

his next suggestion was to bring it in when the sound is there or try record it.

 

I have the same problem as you my shop couldn’t find anything wrong with it

 

UPDATE**
had the control arm loosened from sides that attach to the body of car, suspension got loaded then arm re-tightened also had the bushing and ball joint sprayed with some grease and so far so good has been about 3 days. Mechanic mentioned he has never had to do that before. The spc video on you tube does advise on loading the suspension, either way its better and the noise seems to be gone.

 

I have this same issue and it’s drivig me crazy. Does it also make like a pop/clunk sound in addition to the squeak? For me I hear it when I hit a bump while turning. Really it’s like when the weight of the car shifts.

 

no the sound i was getting is more of a squishy/squeak sound like when rubber gets compressed . Check your ball joints and grease them up also your bushing if haven't done so. a pop clunk usually relates to links check those out
