Rear F Sport sway bar was installed (PTR02-53080), with new MOOG K750288 rear Problem Solver end links. I've noticed when vehicle is somewhat pushed hard around a turn, the rear breaks and doesn't stay in place. What other suspension components might be checked or needing to be replaced associated with the handling characteristics
being experienced (shocks etc.)?
Likely need a better bar up front. Get an IS-F bar or an OEM Sport bar from 2011 - 2013. Or the aftermarket F-Sport...

Thanks for following up 2013FSport, I appreciate it! Apologies for not stating previously however, new Michelin PilotSport A/S 3+ tires are installed as well.
So you believe that the upgrade to rear F Sport bar is causing he rear to "break loose" when pushed through a turn, and replacing front OEM bar with the front F Sport bar (from PTR02-53082 kit), or front OEM bar from 2011 -2013 IS F will keep rear planted more firmly. Will locate and install to correct then. Again, thanks for follow up and recommendation!
Apologies for not inquiring in previous reply however, is the OEM front bar from 2011 - 2013 IS F the same diameter as the F Sport front bar from the PTR02-53082 kit?
^^^^All front ISF bars are the same OD as the F-Sport kit front bar. See Post #1081 above.

That's what I had thought however, was unsure and may have misunderstood with the following reply; "Likely need a better bar up front. Get an IS-F bar or an OEM Sport bar from 2011 - 2013. Or the aftermarket F-Sport..."
Interested in front F Sport bar form kit PTR02-53082, should a CL member have one available for purchase!!
I can't say for certain. What I do know is mine is setting with this part number as read from the shock. What I can say is these offer a great balance of compression and rebound damping. I would absolutely buy them again. Well if I knew what the fronts were that is...
Rear:
Tokico #48530-53280, which seems to map over too this 48530-80574 X2
Apparently I didn't get the front part number and it seems all the site show something different, so no clue what I have up front. I do like them. Front:

Two years new'ish 350 front sway bar end links are making captain crunch sounds. Anyone know what the difference is between these two? The bottom cheaper ones also fit the IS-F if that helps. Front F-Sport bar took their life early.
I installed these just shy of 2 years ago. Cost was $60 then.

I'm runing the Moogs fronts on my AWD. They're definitely more studier than OEM. Being my car is stock height I have managed to kill the rear OEMs. I'm going to replace them since the last time I un bolted the allen hex rounded out.

How did you determine the links are making the sound and not other suspension parts like shock mounts, control arms, etc.?

I disconnected one side, zip tied it to the lower A-arm, sound is gone. Then when when the joint is rotated, it feels like gravel. Oddly, only one side.

For me only the top part numbers were a fit so I had to return the f-sport links and get the regular links for my 2009 is350. Lexus dealer helped figure that out. Anyways that was my story.
Since you need to replace the link(s) talk to the parts counter guy. If he’s no help speak to someone who can tell you the difference between the links.
Torquing the link nut is important since the rubber part needs to twist often. Good luck.
Reviving a very old thread here after weeks of scrolling through 75 pages of this and along with other resources: I'm sharing my experience with the F-Sport rear sway bar which I cannot believe I didn't do this 6 years ago when I first got my 2011 IS350 F-Sport RWD... I bought the rear sway bar (PTR02-53080) online from a local Lexus dealership and surprisingly, the rear sway bar did not have the F-Sport logo anywhere on the bar. It was packaged as TRD instead of F-Sport (which I don't mind cause Toyota=Lexus) and only came with the two bushings. The logo doesn't really matter as the bar will be underneath the car but I'm just saying.
However, I will say that if your 2IS is lowered, it's highly recommended that you get adjustable sway end links because the position of the sway bar is not parallel to the ground/at a 90 degree angle. I found that with the OEM sway end links, the sway bar is pointing at 2 o'clock/10 o'clock position instead of 3 o'clock/9 o'clock position. I've been hearing some noises in the back that was not there before the install and I'm pretty certain that it's the endlinks. My is350 isn't slammed, it's just lowered enough to close the wheel gap. I was researching between Sikky and FIGS and decided to spend a little bit more to go with FIGS because I read that some other 2IS owners found the Sikky endlinks to be longer than the OEM endlinks although Sikky's were adjustable. I ordered the FIGS endlinks from them on Fri and will be here tomorrow so I'll get those swapped out.
