Hi, I'm new to here and wanted some advise if anybody experienced this.
I have a 2013 manual Scion FRS / 86.
About 2years ago I installed TRD lowering coil kit (springs) on my stock KYB shock,strut kit. The KYB shock/strut kit was brand new also at the time just two years ago but now my cars tire makes screeching noise when I turn at a corner at very low speed like 5kmph, just slowly turning at a traffic light but tire sounds like I'm going at 100kmph drifting. I installed new sway bar links and tire still has tread. I brought it to my mechanic and he said my upper strut mount is worn due to the TRD spring that I installed and its causing higher spring rate so the KYB regular strut mount got worn so therefore its effecting the tire noise. Is that true? and what solution I would have? My mechanic said I should install aftermarket strut mount so it can withstand the TRD spring rate but when I called around for aftermarket strut mounts, they said most of them will only fit aftermarket coil kits like TEIN,etc and not on a regular KYB. I was thinking of getting a TRD strut mount but I heard it only fits JDM 86??? Mine is N.America. Has anybody installed TRD lowering springs and had there other suspension parts damaged due to it? Any advise would be great please!
