I only replace my rotors with OEM or BREMBO rotors and have never had any issues! 95ls400, 2004 ls30, 2014 ls460 present.

The OEM rotors are super prone to warping.

I do respect your opinion. A little research might convince you of the benefits of a thin layer of anti seize on both the hub and wheel sides. But even if you don't feel like doing so, the benefits are small for a normal driving situation.

Apparently you haven't read my attachment regarding rotors warpage. Please read under "Do Rotors Warp?"

You clearly didn't read my post in which I already explained the same thing before you ever posted that:

"Warping" is the industry accepted term for what he is experiencing which is distribution of pad material on the rotor that causes a pulsation when braking. Its an argument of semantics.

In my experience with these cars the OEM rotors or at least the rotor/pad combo is prone to warping. Replacing the brakes with centric rotors and centric ceramic pads did away with the issue, but the OEM brakes always warped within 10k miles for me.

Warping is not an "industry accepted" term it's constantly parroted ad nauseam, incorrectly. Warping means warping not pad material fusing to the rotor. A cylinder head warps, a rotor does not except under extreme conditions which will never happen on a street car.

For anyone doing brake work a took like this is essential

Arguing about what this should be called doesn't help the OP.

So, can't compare different models but it's perfectly fine to compare brands in the same thread...you guys are funny.

Are you saying these front rotors from FCP are mid level ?

Not sure why that was directed at me. What did I have to say about different brands? I said the base LS460s are underbraked and they are prone to warping which was my experience with the two I had

The OP has the base car so any discussion of the F Sport wouldn’t make sense.

I'm saying those are below mid level rotors. These are mid level rotors.

I will admit, I drive fast on the highway, but I'm like a little old lady on local roads. ONE time, I totally know what happened as I drove into a puddle in front of my house and the steam coming off the rotors was A LOT. Next day, warped.

I've tried OEM, Centric and whatever brand my mechanic gets... probably Raybestos or similar. They replaced the rotors under warranty at about 4 months. But then those replacements warped in like 6 months, and I tried the Centric. Those lasted the longest, at about 18 months, but now as soon as they heat up a little the "massage" begins. I pretty much know when it happened there too. I was doing about 85-90 and had to slam on the brakes hard. That one incident warped them.

I never had this issue with my LS430 which is still being driven by my daughter and still has silky smooth brakes.

2017 LS 460 RWD. Driving rather fast, so aggressive braking from 80-90 when getting off the highway is not unusual. Installed OEM rotors and pads just over 2 years ago and so far no issues whatsoever.

Stock S8/W12 brakes are 400mm floaters, optional are CCBs. You have 380mm below that for all V8 cars, then 365s on some euro specs and 330mm for V6 and hybrid cars.

So yeah, 380mm is the mid level brakes. Lexus extreme top end stops there.
