Default Brake Part # Help

Hello! I have a 2019 RX350 FSport and need to replace the brakes. Can you advise if the part numbers below are correct and if you can also provide the part numbers for the shims.

* Front Rotors: 435120E050
* Rear Rotors: 424310E060
* Front Pads: 044660E060
* Rear Pads: 0446502500

Does shims come with the OEM pads? If not, can you let me know the part numbers for the Front and Rear Shims?

Also, is there any other hardware I need to purchase such as clips and pins and the part numbers.

TIA!

I have attached my service spreadsheet which includes all of the p/n for my 2020 RX.

Wow...thanks for the spreadsheet. That really helps! Btw...no other hardware required (clips or pins) that I need to purchase to do the brake job? I would rather purchase everything at once then to make another trip to the part dept. Thanks again!

I reused the shims after cleaning but you can buy new if you want. Everything else that you need comes with the pads.
Those p/n are the ones that I use. Sometimes new p/n supersede but these are all of the parts that I purchased. I buy online from Lexus/Toyota dealership, or local if they price match.

BTW, Viktor usually shows all p/n with any repair videos that he does (he and CCN are great for Lexus/Toyota owners).
