So my 99 ls400 has warped rotors so I'm looking into replacing them with a slight upgrade. Ceramic pads maybe a dimpled rotor. Just wondering what everyone else uses. Thanks in advanced for any replys

Welcome to Club Lexus.

The OE pads are ceramic though there are other compounds that may appeal. This past thread:

The stock rotor blanks are fine for everyday commutes. On most everyday driven cars, this isn't an issue that will be obvious, save your $ and get a rotor from a reputable manufacturer. Lots of discussions about "gassing" where the "benefits" of slotted and dimpled are talked about and debated.

Front and rear warped rotors?

Just rebuilt my front and rear brake calipers using Toyota kit.

Whomever performed last brake job failed to use anti-vibration/squeak shim kit.

Used all OEM parts; rotors, pads, fitment kit, shims, seals, slide pins and brake hoses.

Very satisfied with results.

A few more $ but not going to chance aftermarket stuff.

The previous owner installed rotors of unknown origin, so replaced with OEM rotors.. manufactured in Japan.

That's exactly what I needed to hear so il get some akebono pads and try to figure out what brand of rotors would be best for me

i use akebono pads and oem rotors... quiet, smooth, plenty of stopping force

I was going to say what other said, but they got you covered. Slotted rotors are useless off the track, and detrimental for actually putting commute miles on the car. Good luck! Thanks to the others who knew the correct answer to what brakes to put on the car

for the rear rotors you can probably save a bit by getting them through toyota instead of lexus, since the LS shares its rear rotors with another toyota... the MK IV supra!

Do the front rotors for the LS share parts with another vehicle in the Toyota brand?

unfortunately (but also fortunately) not

I guess this probably comes up from time to time, but "warped" rotors is a misnomer. They are too strong to just warp; what happens is that their surface gets unevenly used up and there is a difference in friction which cuases the feeling of a warped rotor. This can easily happen if after hard braking you stop the car, while the brakes are scorching hot and then you stay like that, with pads pressing against the rotor and nothing moves for a few minutes. Do that a few times, with a bit of bad luck, it may stop at exactly the same spot and that spot will be different from the rest of the rotor, and its friction will change which will give the vibration during braking.
That's why people resurface rotors - once you remove that top layer of metal, it is all good again (except buying new is only marginally more expensive than resurfacing... so I always just put on new rotors).
But, most important thing I've learned is that certain suspension components can make your rotors behave as if they are warped, most notably - strut rods (with worn out bushing).
Combination Akebono (ceramic pads) and Centric rotors seem to work great on our cars.

yea the oem rotors and akebono pads work great
