I've realized that a camber correction kit is now in order for my GS. I'm about 2.5" lower on BC Racing Coil Overs. The front inside tire ware is now prevalent and camber adjustment is necessary.
Speciality Product Company (SPC) sells the control arm with the adjustable ball joint . However, I've stumbled upon a useful fact and that is our upper control arms shares the same OEM ball joint with the 2001-2005 Lexus IS300. *The control arms are different widths.*
With the IS300 you can press out the upper ball joint and install the adjustable ball joint, but has anyone with a 2GS done this with their upper ball joint?
