You might want to double check that! The shape is different and I believe the diameters are different as well; similar in performance, but different in size. The 350's bar will be a little stiffer. Not noticable or worth the upgrade unless you are swapping out the front as well. In that case you should change the rear to keep the matched set.

The rear F-SPORT sway bar for the AWD will fit both 350 and 250 RWD models. It is the same bar that comes with the full package.

Default Rear Sway for ISF
do you guys know if the IS350 rear sway bar is the same as the ISF one? If not, what is the difference in the diameter?

^^^^ The stock rear sway dimensions for the IS rear sway bars are as follows:

250AWD - 14mm
250-350 - 15mm
ISF - 17mm

F-Sport:

250AWD - 17.5mm
250/350 - 19mm

According to another recent thread (which had a PDF from lexus attached) that changed last month.

They issued a new set of rear AND front bars for the AWD model that are different from the RWD ones.

I was talking about the rear sway bar for AWD before this new set. Is it the same bar as in the new set?

I've always received confirmation from Lexus dealer's that the AWD rear only was the same as for the RWD models.

Oh well, better for the AWD guys

Prior to the new set, the bar for the AWD IS was indeed the rear same bar used in the RWD set. The rear bar in the new set is something different (17.5mm vs 19mm). I have the 19mm rear bar installed in my F.
