I've spoken to my service guy who's a good friend and drives a GS460 with F-Sport sways and said that the issue is with the bushings and that while the size may be different on the GS and IS, the bushings are the same.

I had the springs replaced on my IS and it cured some of the clunk noise, but not much, so I don't hold out much hope. However now that it's the summer time, my bushings aren't making noise...only when it's cold.

That doesn't make any sense. The front 3GS f-sport sway bar is 31.75mm in diameter and the IS 250/350 RWD is 28.6 mm (3.15mm difference). If the bushings are the same size as the IS250/350 RWD, then the 3GS sway bar would be too big for the bushing, and would probably bind instead of bouncing around causing thumping noises. If it were the other way around... that would mean all the IS250/350's with f-sport sway bars would be thumping all day long. These bushings are really like polyurethane, so there is very little tolerance in the fitment of the sway bar.

WOW! You've got a lot of extra time on your hands to be doing that kind of math/homework. Since this has become a pissing contest about "who's sway bars are bigger"...I'll just leave this thread alone. However, I thought Clublexus and forums like this were to come and share knowledge, issues and help to fellow Lexus owners be-it a GS, LS or IS. Since my first post, Wingster, you basically told me this was a "GS only" thread. Hate to be a cry baby...I just hate when threads turn into guys who try and take people to school instead of help out and realize that we're all dealing with the same issue regardless of the car or sway bar size and we want it fixed...plain and simple.

i think you are taking what wingster said the wrong way. he has his points about the bushings and valid concern on bushing. bushings should be specific to sways of different diameter, if it's too big, there will be noise. if it's too small, it will bind. clublexus is a place where people try to help each other out and share information. and that's exactly what he's trying to do. in no way was he trying to ditch the IS for having smaller sway bars.
pjjames1: This is not a pissing match, I apologize if you took it the wrong way. I'm just trying to share information that I've learned. I don't know why you feel like I took you to "school". You know that we are in the in thrid generation GS section of the forum. And that this thread was started as a subject regarding a specific "pending" TSIB a few of us are waiting for.

still waiting like suckers. I am so done with F Sport its not even funny. Their intake for the 3GS is trash and the sway bars make more noise than my crappy intake. Once they fix this I am avoiding F sport like it has a disease

jeez..? Are there any Lexus' representatives r listening to us on this forum? the 2gs was kind of different coz' it was aristo in japan and had the v300 version which is the 2jz-gte engine. that made the car a tuner car and got a lot more attention from the tuner companies
now regarding lexus' fix on the fsport sways? i have been asking the same question too, this is unbelievably long time to fix which i consider a relatively straight forward matter

Another quick update:
Temperature in Dallas just took a dive to the low 40's overnight, new F-SPORT bushings held up to the challenged... still FREE OF NOISE!!!
EXCEPT the damn brakes is bytching again!!!
Off the topic..
Should I ask them to put the OEM's "HIGH FICTION + HIGH DUST" brake pads back on my toy, just so I don't have to be bother with the freaking brake noise!?!
Thanks all,
Stevie
