IssaV8 - I love the cat's look!! Like "mom, is this a toy for me?" (lol). I wish I lived closer to hear your exhaust in person - I am so tempted/itching to replace the exhaust but I am just worried that it will give me codes etc but the itch is real and not because of the cold and dry weather

you could always start with just an axleback- should not give any codes at all since the sensor is unbothered! I think I’d rather have some more cold and dry over all this rain.

If all you're doing is replacing the axleback or midpipe, you shouldn't get a code.

I have the gt haus axleback and no codes. Plus gives it a badass sound without being too crazy loud.

For the people that have done this so far, can you comment on how the brake feels has changed? Does it have a shorter pedal travel? Is the pedal firmer?

any updates for '23 RCF rear brakes? it was stated that the newer models have an e-brake...any confirmation? i'm hoping this will resolve the message on the warning panel/screen.

The online parts ordering systems that the dealers show us (as consumers) don't show anything for the '23s yet. The dealers may be able to order on their side, but no '23 RCs have been delivered, so parts availability may be limited.

Found this thread from somewhere else. Just an FYI for those doing the swap that the RCF/GSF brake lines are kevlar so in reality if you are changing brake lines, I'd go that route over s/s. The s/s would be a downgrade to RCF/GSF stock lines. Not sure what lines you have now but if they were the same, one wouldn't even have to change them.

I was going to change my brake lines to the Tom's s/s lines (mainly because they look awesome, and they are Tom's) but after a lot fo research and seeing a picture on FB of someone cutting a stock line in half to verify I saw zero need to swap out lines to s/s. Those that have done so in our group also noticed zero difference in pedal feel from the stock lines which tells me that our lines are actually decent... lexus/toyota actually thought it though on that.

Nice thread though! Retrofit are always awesome to see. You might even get the rotors cheaper from someone that is going two piece rotors and took their stock rotors off. RB racing and Girodiscs are two nice two piece rotor options that pair really nicely with the upgraded brembos... plus you save about 25ish lbs of rolling mass :-)

for the rears, you will have to buy pre 2021 oem brake lines to work with the brembo calipers. the stock 21+ lines are flipped around. hard to explain but once you have it in your hands, you'll understand. other than that. these are nice OEM upgrades!

I always have ideas but not the talent to make it happen haha. Wondering if anyone could make some mount or something to run the rcf rear calipers and another small caliper just for the ebrake. Wiring would be easy. Just the brackets to hold the calipers on the correct spot.
