I bought my 2 about 4months ago and it had been having wandering problem at 60mph+ since I bought it. Last week I took it to a shop and had the alignment done. After that it was good for about 3days and the wandering seems getting worse and worse. My suspension setup is KYB AGX shruts, Eibach Prokit springs, TRD front & rear sway bars, Enkei RP02 17" wheels w/Proxes FZ4 tires. Also I was told by the shop that the left rear ball joint is worn slightly. Any suggestions? Thanks a lot!
