I want to review it to see how close it is to '21+ IS or 4GS system EPB system...

Way different systems sadly

Shoot thanks. Looks just like how GSF is setup.
I think we can complete forget about '23 RCF as a solution at all now. (Will be a major retrofit that can be potentially done but not everyone will be willing to)

All works fine, i am waiting on my custom built cables for the actuators to plug into so i can clear the error codes, but the brakes work well. Remember there is no solution for the EPB to function.

I’m just sticking with the stock lines, after reading a lot of the posts on here it dose not seem necessary. I got the factory brakes pads, not trying to do anything aggressive with the brakes.

RCF OEM Lines or SS braided lines would definitely be a good upgrade. Your brakes will feel a lot firmer. If you ever take the car to the track or get your brakes hot doing some "spirited" driving, you run the risk of bulging a line. Granted it's a very small risk, but for how cheap lines are I would do it just for the firmer pedal.

Nice!! I got mine (front and rear) a month ago but still haven't installed them. I'll be installing just the fronts as well but I will ceramic coat them first. I got the rears just in case there will be a solution and wanted to match the fronts. lol

I forgot to mention, since its related to the brake upgrade. Did anyone figure out the right spare tire to run and clear the fronts? I was looking at RCF/GSF spare but was wondering if there is any other options that can fit in the 2021+ IS.
