I just got a notice that said mine are on back order unfortunately. I am not sure what you mean by TSB is no good. The parts will still work on our vehicles even if we have all aftermarket parts currently. TSB isn't a guarantee of the dealer replacing them even if it was all OEM right? I thought only recalls do that.

Update:
Washed the wheels early Saturday morning, it squealed loudly with the first initial braking, then that was it. That was expected with the rotors getting wet during wash. Drove around all weekend. No squeals at all. And an added bonus, there was very little brake dust. I'll update again once I get another 500 miles on them.

Just my Luck, I was in the same position as you, tired of the Akebano ProACT ceramic shreeeeek!!! I had them for 3-4 months and I installed some new OEM Pads about two weeks ago with the same shims you received. However, it looks like I got the old breaks (30491)… For the most part it is night and day difference. I hear the squeal once or twice in the cold on my morning commute, sometimes never. The important thing is that it’s nowhere near as noticeable as it was before and I honestly might only be hearing it because that all I have listed for while breaking, the last 4 months of my life. Also the Bite is much better, I feel like I kind of had to re-learn my brakes!
All in all I’m just seconding what kennyD has already told you. Switch back to OEM, deal with the dirty wheels and enjoy the quiet/better bite. You won’t regret the $80-$100 you spent.

Reporting in on my set up described above. Though I do not have the "new" pads from the TSB (missed it by a few weeks) I did get the same Shims as kennyD. Since I wrote my last post, any squeals have I mentioned have gone away. The dust is back :| but no god awful squeal. Just throwing this out here because I think the biggest difference in the sound department is the fact that kennyD and I switched from ceramic back to OEM semi-metallic. Maybe the shims too.

You guys are giving new hope. Just setup an appt with my boy Tommy this weekend to swap out these pads. I don't care if these pad produces more brake dust, I'll just wash the wheels more often.

Btw. The new pads haven't been dusting nearly as much as I remember the original OEM ones. It rained all day in dallas/fort worth today, so I have dirty wheels again. So this week won't be a good one to check on brake dust for me. But I'm glad that you've gotten a fix for the squeal. Please keep us updated on your brakes in the upcoming days to as to if it is a long term fix.

FWIW, my wheels are coated with Gtechniq Wheel Armor. I don't find it easier to clean, just easier to dry with a blower once they're thoroughly rinsed. What does work really well for me on removing brake dust is Sonax Wheel Cleaner Plus. I have this in a 3L jug because I love it so much.

My brakes and shims (from the TSB) just arrived yesterday. Hopefully I'll get them put on this weekend. I spoke to my mechanic though already and he said that it will not be necessary to resurface the rotors. I explained the reasons why per this discussion here. My rotors aren't very old. He feels a this point it won't make a difference and I'll be sacrificing some life of my rotors. He'll do it of course if I want him to.
I could always just have the brakes put on. See how it goes and if I get the incessant shreek, then I just go back and have the rotors resurfaced.
Your thoughts?

Do it once, do it right. Don't fools around.
Good luck.

I will add that if you decide to resurface, our rotors are just a tad larger than many lathes can handle. Make sure your mechanic has the right brake lathe that can accommodate our larger rotor diameter.

Yeah it does show double shims. Which I think is not correct. Because if you you look at the way they're designed, they really can't be layered, the retainer hole would not line up correctly. The bent portion wouldn't sit correct on top of another shim. I pulled that diagram directly from a Lexus parts site. These shims are thick, they have a layer of rubber (at least I think it's rubber) on the side that makes contact with the pad.
