Do you have any info if it will fit on AWD version too?
Thanks
I have no clue but I do not believe the brakes are different among the AWD and FWD models. From what I've looked around, the AWD and Base models run the same type of brakes and the 200t and 350 models have the larger front brakes. the rear brakes are all the same in all the IS of this generation. Therefore, the mounting knuckle MUST be the same but i have not physical verified this myself as AWD models are rare in my area.

can anyone confirm this?
I can confirm the 3IS front rotors and backing plate are different between the AWD and RWD models, regardless if it's a 250, 200t, 300, or 350.
The rear brake rotors, pads, shims, calipers, and backing plate are different on the 250 compared to the 200t, 300, and 350 (those 3 are all the same).

The rotors are different on AWD and RWD but the brake calipers are the same.
I wonder if the offset is the same then the IS F rotors might fit AWD too.
So now can we confirm the IS-F will fit and perform on a 3IS RWD?
The main difference is the cooling vanes are fed from the outside or inside. Lexus has used the "AWD" rotor on AWD and RWD models, while the "RWD" rotor will only fit on RWD models (due to a smaller hub clearance).
has anybody attempted to fit RCF/GSF brakes onto their car? i kinda want to do that once i get my car tuned and headers installed i like the look of OEM F brakes rather than RR Racing
How are you planning on evacuating air in the line from when you disconnect the stock calipers? Apparently you need Toyota software to properly purge the system. BMW is this way with the E46, too. I've always done a standard two man or pressurized bleed on that car though and it seemed fine? Anwyay as far as software I am guessing you have this? I need to look into that at some point cause I want to replace my fluid with some German stuff.
Also very very neat install. I'd probably wear through those like butter. $200 each for rotors and $500 for pads is a lot to swallow.
I'm currently at $54 ea for rotors (German stuff) and stock pads (also German stuff) at $55 for the set.
$160 for a front set of brakes and 45 min to change out is a steal for me!
There's nothing special about the braking system on these Lexus. I'm doing the standard 2 man bleeding procedure which is the same toyota/lexus dealerships are doing. I have friends that are honda and toyota dealer service techs and there's no issue doing it this way. I've done dozen of brakes and bbk upgrades since the late 90s and never really had any issues with any car. If you want to get all technical, you can purchase a vacuum bleeding system and pull the brake fluid.
This entire process is not much different than IS250 owners upgrading to IS350 front caliper.
As for rotors, I went with stoptech drilled rotors for $92 each. The pads i'm using are stoptech street front and rear were around $100 shipped.
OEM lexus rotors and pads are way too expansive for me.
As for software, I have techstream. plus these lexus do not need anything special to change in the computer software. RCF/GSF have these brake pad sensors that you must swap out and you have to reset the sensor in the computer (I think??).

Yeah but the stability control system has a pressure regulator, valves, etc that needs activation by software to purge it cause air gets trapped inside. Common on modern cars.
Correct, but when doing a caliper swap, you're pushing air out of the new caliper and not the entire BMC. brake upgrade and BBK install have all been the same throughout all cars/users on this forum. dozen of members and threads of people doing swaps and bleeding brakes perfectly fine without any software changes.

yup, thats correct. nothing special or need the techstream if you're changing the brakes/mbc. only electronic brake system/hybrids need it.

I am saying if you want to do a full and proper fluid replacement and bleed since you are installing new brakes, you'll need the software activation. I am not saying you'll introduce air into the system when doing your brakes. I am saying you may have air in there that you can't get out doing solely conventional means.
Yep, if the system was completely empty. swapping caliper doesn't make the system empty. Just like the many other 350 brake upgrade that other users have done on this forum without any issues.
anyways, stoptech gs350 f sport drilled rotors finally came in. everything in the picture is all you need. no hub or shim needed. Had another buddy install this same exact kit on his GS350 f sport and he used his stock rotors.
