None of the Lexus TSIBs in the Lambros list have been effective in reducing wind noise except for the part that replaces the glass in the front doors. Most wind-noise-suffers have found relief with the DIY fix that is here: http://www.clublexus.com/forums/ls46...noise-fix.html
Yes, part of this TSIB (http://www.lambros.net/LexusTechInfo...L-NV009-07.pdf) retrofits the windows in the front doors with laminated glass. There are no indications that any of the elements of the TSIB were beneficial other than the glass replacement. The glass replacement only applies to all 2007 LS460s (swb only) and a few of the early '08 LS460s. Many of the '07 LS460s were not regarded to have the wind noise problem even though they came equipped with the single ply glass. I am confident that the window retrofit is beneficial but anyone having a problem should do the DIY trim repair first and then decide if they are satisfied.
What I found with the window replacement on mine was the reduction of noise from traffic passing on either side. The DIY Trim fix has been the most successful for wind noise. I still find myself bumping the window down slightly for optimum results.

Unfortunately, for those of us that did not get the glass swapped out, I fear it would be prohibitively expensive now.

Found a little something today at the dealership that I wasn't aware of. If you look at the 2007 photo, you can see the fender stops at the door. But if you look at the 2014 photo you can see they changed the way the fender covers the door opening. It is clearly bumped out in the areas I crudely pointed out. I can't see how they would do this as a design feature because who would actually notice this? Anyway not sure if its been discussed before, thought I'd add it if it hadn't. Sorry the pictures aren't the best.
