Anyone have any definitive sway bar information on the above mentioned platform by chance? All my searches keep returning either RWD stuff, or AWD mismatches or stuff that didn't fit. I was hoping to find the factory sway bar diameters, and any aftermarket sway bar upgrade options. Anyone?

There's only the Rear F Sport sway bar for AWD. Unless you buy the AWD full F-Sport kit F/R. The single rear bar design is a strait bar no bends. The kit comes with rear oem design with bends just thicker 17mm. The strait bar is 19mm.

So to sum it up, the F sport full package (front and rear bars) will drop right in to a 2011 AWD IS350? Would you know the stock and f sport diameters by chance?

And is there anywhere that sells just the rear F sport bars for AWD cars? I keep finding the rwd models.

Check out these links. It has been discussed to death!
There are many AWD sets on eBay. Just choose the right year one. 06-08 9-13 minor suspension changes.

For the AWD there were no suspension changes over the years that would affect installing sway bars. 2006-2013 IS250 AWD and IS350 AWD will all fit, no issues.

Only RWD had differences between 2006-2008 and 2009-2013.
