I had the Whiteline front sway bar. It definately wasn't as simple as installing the TRD rear sway bar.
On the Whiteline front sway bar the end links don't bolt up securly because the thickness of the sway bar is almost double the thickness of the stock sway bar.......I ended up un-installing it a week later and going back to the stock FSB.
I also know a few members on the forum that have had the same problem and a few stayed with the Whiteline FSB, later snapping the bolts on the sway bar end links.
Dunno about the Intrax FSB, didn't even know they made a FSB for the Camry/Solara. Anybody go with one of these yet ? ?
Here is a link to Whiteline if you decide you wanna invest in one.
