Brakes
Team, looking at this setup for my 2000 LS400 with 115k miles on it. Your thoughts? https://www.powerstop.com/product/po...LEXUS&mo=LS400

What's wrong with the current brakes? The stock braking system is plenty able to overwhelm the grip of the tires, so upgrading to bigger brakes won't make the car stop any faster.

Akebono ProACT pads and stock/stock replacement rotors are all that's required.

If you want to change the feeling (aka more bite at the top of the pedal), refreshing the brake booster, putting fresh fluid in and changing to a more aggressive pad will accomplish that. The ProACT that Paulo mentioned are a great middleground - slightly more aggressive than OEM but still a streetable, silent package. This being said - you can only go so far with this. Much of this "feeling" is engineered in by the entire hydraulic system of the brakes. If you want very sharp aggressive brakes right at the top of the pedal, and not the soft linear streetable system that's stock, you need to replace the whole system.
If you want to stop harder\shorter, then you need stickier tires, because that's what's actually stopping you.
If you're encountering brake fade, wow, I can't believe how hard you're driving the car, are you doing this on the street? And besides, bigger brakes won't solve that. They will also fade just like the stock brakes do. The only solution to this is to channel more air onto the rotors themselves, which involves modifying the front fascia and ducting airflow to brake cooling.

I'd say the whole slotted rotors and aggressive pad thing is a bit of a waste of money on an LS400. I wouldn't pay extra for it. I did just install the Z23 pads on my rear brakes as a pad slap. Didn't notice a stopping difference. I installed the stock Akebonos on the front at the same time. The nice thing about Powerstop pads is that they include the brake hardware. Once you buy Lexus pads, shims and hardware, you're probably paying twice as much for stock brakes. I would spring a little more money for coated rotors, though, to hold back the rust.

My thoughts on "Powerstop" is not needed to use. I'd stick to the Toyota original or OEMs that are certified by Toyota. I know the inside of Toyota some and I also know how they are engineering.
