Maybe 2011 and UP different design......?
Also it's AWD, if it makes any difference.
Anyone done 2011+, AWD ??

Does anyone know if the 2ISX50 F-Sport Sway Bars suffer from the same bushing noise issues that the 3GS folks had been dealing with? It became such a problem that Lexus had to release a TSIB to provide different sized sway bar bushings in order to fix the problem.
Yes, there are applications for both RWD and AWD versions. There's only bushing option (PTR02-30100) so I'm assuming the bars are the same diameter, but its going to be in the brackets that the bushing may potentially be the issue. The front sway bar brackets are different. I have no idea if AWD GS owners have had the same thumping issue as RWD GS owners. I just don't know.
By the picture below, one can easily assess the height difference in the F-Sport sway bar bushing. It's approximately a 2mm difference in height between the two.
The newly designed bushings have a "ZD" stamp whereas the old (original) design shows an "AB".

I had various noise issues with the front F-Sport bar in my IS over the years. I replaced the bushings twice and then even tried the factory IS F bushings with the F-Sport bar before switching to the factory IS F front bar (still running the F-Sport rear).
That said, the IS did not have a TSB released for it and it does not use the same bushings as the GS. The IS part number is PTR02-53083.

Just installed mine. I'm not entirely sure but I might have had the updated front (if there was one) since I've seen some fronts have tabs for the AFS sensor and mine didn't have it. Anyways. Rear went on easy, and the front I had to actually swap the sway bar links from each side so they would work with the bar. I have to say, the bars paired with the chassis brace makes a night and day difference.

Just installed both front and rear F Sport sway bars on my 2008 IS 250. Took me about 3 hours total, mainly due to the front was a PIA because of the engine cover removal and reinstallation. Plus, I installed the bushings on the front sway bar the wrong way the first time. 
Had some trouble with my left rear sway bar end link as well, it kept spinning when I was removing and placing the nut back on. No impressions yet because I have not driven around much. The only thing that surprised me was that the front sway bar was so much thicker than the rear (both OEM and F Sport). Installation was straight forward with the included directions.
For those who have my year and model, tools you'll need:
-ratchet that has a release button so that the ratchet doesn't hit you in the face when it dislocates from the socket extender
-17 mm socket for the front and rear sway bar end link nuts
-14 mm socket for the front sway bar brackets bolts (4 total)
-10 mm socket (or phillips screwdriver) to remove the screws holding the front engine cover and the front level sensor (if you have AFS)
-12mm socket for the rear sway bar bracket bolts (4 total)
-breaker bar to break the end link nuts loose
-torque wrench
-safety glasses
-jack stands
-jack
-maybe needle nose vice grips for the the end links if they start spinning while you're taking off or putting on the nut

I have noticed a significant reduction in body roll with the front and rear F Sport sway bars compared to stock. There is some slight body roll; however, I find myself not sliding around in my seat when I take sharp turns with moderate speeds. Can't believe I've gone so long without upgrading the sway bars. Definitely worth the money.

Just got the F+R F Sport bars installed on my car this afternoon. Had a local guy help me out and ended up swapping in new end links F+R because the old ones were on their last legs. The front seemed to be the biggest PITA given that you have to lower the subframe and remove the end links and steering rack connectors to wiggle out the bar.
Driving impressions were pretty amazing. I already had my Michelin PSSs put on the car so it was already very response when turning but with the sway bars the precision of everything has ramped up. The car feels 100% more settled from steering inputs without all of that horrendous body roll from before. It feels less dramatic than previous but is way more fun.
On a side note, does anyone know the % difference the front sway bar makes on the AWD models? I saw a % increase chart on the first couple pages of this thread but for the AWD it listed about a 40-50% increase in the rear but nothing for the front. I highly doubt the front sway bar is the same and is just painted blue. Maybe because the earlier packages didn't have the front sway bar for the AWD model?
