New to the forum but it has already been very helpful in making some decisions. I searched through the other posts and did not find an answer so here goes. Other threads indicated that the F-sport front sway bar is only 6% stiffer than stock. Early press releases from Toyota aligned with that (Sept. 08). Now on Fsport.com, the stats indicate that the front F-sport sway bar is 42.8% stiffer...not as trivial and easy to blow off as 6%. Have others seen this or am I missing something here?

F-sport.com said 6% as well until very recently.

Now it says 6% for the rear 250 RWD bar (where it previously said 42.8%)

I suspect somebody typoed when they updated the numbers to add the other vehicles they recently added to that page.

What about the IS350C bars?
I presume they aren't interchangeable with the IS350 bars?

I'm about to start installing my JIC coilovers, F-Sport sway bars, and F-Sport chassis brace on my IS350, wish me luck!

I just bought the front and rear sways. I bought the "2009MY" set, which is apparently a different set. There are two separate part numbers:

PTR02-53082
PTR02-53094 (this one says "2009MY")

>Maybe they tightened up the front more with the 2009MY sway bar set - or -
>Maybe the "stock" front sway for the 2009 IS350 is softer than previous model years and so the F-Sport sway inherently tightens it up a lot more.

But, the descriptions for both parts are identical (below), so I don't see how the 2009MY set could be any tighter.
