anyone in here doing the BBK upgrade? My 21 F sports requires all new brakes and rotors at 55k miles so figure to spend a little more and upgrading to the 500H BBK. These calipers are the orange for 2026 limited edition.

wow. Nice. I did the slotted rotors & brake pads upgrade on my 4th Gen RX350, but honestly I feel no difference.

You don’t need new brake lines, our OEM brake lines will work just fine. I opted for OEM rotors but you can get after market rotors for much cheaper

Just installed them today by a buddy. I’m very happy with the result as I plan to keep this car until it dies

Yes it is direct fit. Just need wheels size 20 at least. Braking is noticeable difference, especially my old brakes were already almost next to nothing left.

i thought we gotta change out the dust shield too? I remember looking at it but i was on tight budget back then so i opt for just original brake job and didn't go with bbk. I added everything up i think its around like 1k-1.2k for everything. The most expensive is the oem 2 piece rotor.

i did order the heat shields which cost relatively cheap but the labor or taking off the entire hub ring on a 4-5 year old car is just not worth it. To solve the problem, just slightly bend the end of both sides a little and the new calipers will fit right in without any issue. Yes the OEM rotors are the most expensive items. I plan to keep my car until it dies so I don’t mind spending more for OEM. As I mentioned earlier, you can go with after market rotors which cost like 1/4 of OEM

Where did you order the orange calipers from?

I'm trying to go for the same look!

lexuspartsoutlet.com, good luck getting them though cuz it was a struggle since these orange calipers are very limited. The black ones are widely available and you can paint them of course.
