with stocks wheels and 3 piece wheels!
So bad I am thinking of getting rid of the car
Wow, are you sure it's not something else going on with the braking system? Did you do all those rotor and pad swaps yourself? Might be time to suck it up and have the dealership or independent mechanic figure it out.

Good to know. How is the brake dust with their ceramic pads?

Ok khizr23 I'm confused. In one post you said you didn't use the pads I used and you had no issues. In the next post you clearly said you used the R1 pads and had no issues. Which is it? I have the R1 ceramics and they are squealing terribly.

I ordered those same R1 rotors and pads, but when I took the wheels off to do the brake job I realized that my rotors were mint, so I just slapped the R1 pads in and left the stock rotors on. No squeal whatsoever.

What in my message makes you think I did the work myself? What makes you assume that I didnt have the dealership do the work and a mechanic?

the car brakes without hesitation, however the noise is unbearable. I used all oem parts twice that only lasted about 6k before noise, then I went EBC same thing, then I bought centric with semi metallic and ceramic and noise on both. Lexus techs can not figure it out how ever they say F sport have that issue blah blah. And to spend on a brake kit is just a little to much effort in making sure they fit my offsets for my existing wheels.
On the forums its some do and some dont.
Conatcted lexus and NO resolution, they say it is a wear and tear part, howver on a 50k plus car at 6k miles brakes wearing out is unheard of to me! Keep in mind I am slammed on rubber band tires,22x9 on a 225/30 and 22x10 on a 245/30 so driving fast and heavy braking is not what I do. however , they have been calling up the yin yang to offer me deals on a new lexus. this is my 3 rd lexus and never had an issue till my 15 GS Fsport perhaps its time to move on to something else.Another brand

tried oem rotor with oem pads
oem rotor ceramic pads
oem rotor semi mettalic pads and so on
hawk pads
oem pads
bendix
wagner
oem 2 puce rotors
oem 1 piece rotors
cebtric rotors
ebc rotors
same result
oem wheels
3 piece wheels
actually started faster on the oem 19” wheels

all after a few miles made noise.
My friend is350 F sport did the same.
I have a feeling the calipers are at fault in the Fsports. I drove a LS500 f sport a few days and same sound but only a bit quieter.

was on here to see if a fix was found. Thanks for the input.

the caliper doesn't make the noise, its either the shim kit, rotor or pads made the noise. the caliper just push the pads onto the rotor.

I understand that, but after changing pads and rotors it has to be something else. But at this point I am pretty much done.
Trade in for something else.
