Hi guys, just became an owner of 2019 rc350 f-sport awd, excellent car! It doesn't have the factory orange calipers option, as I know those were offered to rwd models only. Does anyone know if the orange calipers would fit the awd?
As I see the difference is between the wheels being staggered on rwd vs all the same on awd, the brake system looks the same, but somehow the orange calipers are not listed as compatible to awd... I'd go ahead with this upgrade with no hesitation if I know they fit, not a fan of powder-coating by 3rd party.

 

Front rotors on the RWD F sport are larger than the AWD and non F sport models. Not sure if the size of the rotors impacts fitment of the calipers.

 

Ok I got some (wrong) feedback from Lexus dealer and ordered the orange calipers. Tried to install today on my AWD, and apparently they are meant for larger rotors, even though they bolt on to the knuckle just fine. . The look is great, and I really want to keep them, so my next question will be - how easy is it to upgrade to the RWD large rotors? I guess these are the two-piece ones right? I'm sure I'll need the large brake pads (if anyone could give me the partnumbers it would be great). Will I need also different dust shields? And wondering if the knuckle is the same, as if it's also different then it becomes too much of a hassle. Here are before/after photos, on the same rotor. You can see the orange one sits farther than the original black one. The orange calipers sits a little tilted, I hope that is normal.

That tilt in the caliper doesn't look right. A larger rotor is not going to solve that and you want the whole pad making max contact with the rotors.

 

Yes thanks! Apparently, a lot of parts are different so this conversion cannot be done. Not even considering that rotors should be replaced by the large 2-piece ones, large pads, dust shields to be replaced by larger RWD ones, the biggest problem here is the knuckle! It's conceptually different between AWD and RWD, especially the mount points of calipers, which makes this project impossible. There are no adapters avaialble. There was one mention about RC-F big brake calipers and rotors fitting AWD models with no modifications (while for RWD you have to go with adapters), but it is too expensive of a project for only visual upgrade, so definitely not something I'd pursue.
So, going to a different path - as all the original calipers are already off the car, they will go to the local reputable powdercoating shop to be coated and back. Will try to return the orange ones to the dealer who mislead me, even though I provided VIN and asked in the email, order note, by call, that they verify if those fit AWD or not. Hope they will admit the mistake.

 

Wait, so is this true? That I can upgrade to RCF parts for my AWD RC fsport?

 

We'll find out. I just order ISF calipers and have IS500 rotors sitting in the garage.
