Default 1998 Lexus ls400 brakes kit

I have a 98 ls400 that needs new rotors and pads but idk which would be best for this boat.
Drilled and slotted, slotted or just the regular rotors ? Help !!!

Regular rotors. Drilled and slotted don’t give you any performance benefit, will be louder and more prone to cracks. They are cooler to look at though

Regular rotors will do just fine.

I think the OEM are pretty dang good.I think the pads are what matters here.Scotty Kilmer advises Akebono.

I replaced all 4 rotors and pads two years (10k miles) ago:

Bosch QuietCast front rotors (not slotted or drilled)
Centric Parts Premium with e-coating rear rotors (not slotted or drilled)
Akebono ProACT pads on all the way around

I had no problems with quality out of the box, and continue to have no issues with any of it other than just recently. I'm starting to get a little bit of squeak at low speed braking and only at certain pedal pressures (pulling into my garage, or creeping forward at a red light).
But hey, used brakes squeak... brakes are a wear item... I wouldn't say this noise is an unexpected issue, just something I have noticed lately, and should be easy to fix whenever I feel like getting around to it.

Like YODAONE said, you can't go wrong with oem.
Like Dave said, don't do the slotted and/or drilled. Unless you are taking your car to the track every month trying to set better lap times, drilled and slotted rotors are over-hyped and an unnecessary cost. They do start to crack MUCH sooner than plain rotors.

Your existing shims can be re used especially on the rear as they only get approx 30% of total braking power and wear much slower than the fronts do.
Some aftermarket pads come with shims, not sure about Akebono...
