Some came with RSB's, some didn't. I think it depends on the trim level. I know i have one on my Cam and it was the lowest trim available in Australia. IMO t's pretty pathetic and the links from factory are plastic.
wow... never even thought of a rear sway bar on my Camry. I never noticed much lean so I figured either it already had one or is was just a light car. Now you got me looking under my car! And nope, no RSB on my 90 DX 4-cylinder. But I'm heading back to the wrecking yard today to grab one because they have a couple V-6 cars from 89-93. I'll check online before I go to see what years will work on a 90. Thanks for the cool idea.
