Merely a suggestion. If you've had your caliper powder coated or painted or a planning to have it done, then replacing boots & seals what to do. Although, if painting you can work around replacement.

Centric 143.35037 is also a good part number for the seals and dust boots kit. It fits a wide array of vehicles.

buy new calipers and call it a day and most people would suggest you do it in pairs.

that’s what I did (buy new caliper in pairs).
and when you do that, buy by new banjo bolts and crush gasket and flush the brake system.

Also, try getting anywhere close to the same level of customer service from the dealer compared to @FIGS .

you need TWO. one for each front caliper.

They're oem brembo. it's cheaper to buy them in a pack from the dealer than buying singles.
There’s another part number


04478-0W050



https://www.lexuspartsnow.com/parts/...478-0w050.html

Is this an updated part number?

04478-0W010 doesn't change up but 04478-0W050 appears to be the same thing. Why not simply order 04478-0W010.

Double checked and it seems these dust boots are for the RCF track edition.

Original Brembo seals can be purchased at Addiction Motorsport in the UK. They also sell original Brembo pistons. Albeit not all 3 sizes (38/34/30x32) with the Nickel coating but with Porsche spec coating which seems an anodized coating.

The Nickel coating will flake over time and cause corrosion issues.
