Brembo RCS 19 and Fren Tubo Brake Line Upgrades

Here's my experience, as a data point for consideration. I run the bone stock 2019 V4 brake setup with the exception of Motul 660 fluid and Vesrah XX pads and think the performance is very good and not holding me back at all. This bike is exclusively used for the track and I'm just now finishing my first season of amateur racing at CVMA. The ABS system is intact and very good I think and it's only intervened on me twice while trail braking way too hard---and probably saved me a low-side. Two very trusted sources have shared that plugging the ABS affects the engine braking, as the software is so sophisticated that engine braking is tied to the brake pressure, as read by the ABS module. That said, I know FAST Ducati guys who've plugged off their ABS and have no complaints at the track, and like the firmer lever, and recommend doing so. I routinely hit 1.0-1.1Gs braking and have hit as high as 1.6 Gs up the slight incline into Turn 1 at Big Willow. I have experienced just occasional and slight brake fade on very hot days on the main straight at Fontana, but that is during max braking efforts held for several seconds coming down from near 180 mph. From a stock system, I think this is pretty impressive. Good job Ducati! A friend let me spin some laps on his Ducati V4 that had no ABS and a higher-spec master pump and Z04's and I did not go away thinking it was a better setup than mine. The feel was different for sure, way more on-off, but I can't say better or worse, and I guess it just depends on preference and what a person is used to.

For my purposes, which is to get faster and achieve some podiums in amateur class club racing, I know there's another 3-5 seconds a lap that'll come just from improving my riding first. That said, racing is teaching me that it is very good to continuously try out new stuff, new kit, and new setups. I guess, for best results, the bike, along with the rider, should be continually "developed."
 
Even on the 1299 the ABS was awesome, probably saved my bacon at least once. The "idea" of no ABS on track might appeal but in reality its not an issue, in fact I liked trying to activate it so that I could test my limits :) You would have to be a hard charger to need remove it to get improvement over the stock setup but a starting point may be upgraded lines and pads and turn the ABS off. Fluid is virtually incompressible, so cant really see the point of ABS delete unless you can ditch the pump and associated weight.
 
It is wrong, Brembo designed the 19 and the 17 for different brake caliper piston size, it even says so in their product specs. I don't understand all the people coming on here mis-matching Brembo products against their own recommendation.

I read the same thing about the 19….which is why I went with the 17, which for me is perfect with the Stylema’s….the stock MC felt way to squishy for my tastes…
 
I've bypassed my abs because the feel is immensely better for me, but if your keeping the abs, perhaps the 19 wouldn't feel as abrupt, idk. I've gradually changed my braking system so I did see what effect the changes had as I went. Going from the stock rotors to the t-drives wasn't noticeable, going to iron rotors was very noticable, and replacing the caliper pistons got rid of the brake fade. I now run a billet evo 17x18 mc and the gp4ms calipers with zo4 pads and use endless bf.
 
One final point: The principal reason that Ducati engineering selects a master cylinder piston size that results in a softer lever modulation feel is rider safety. On the street, when a rider experiences an urgent situation that requires emergency braking, the tendency of an average rider is to grab a fist-full of lever and lock-up the front wheel. A softer lever has the same stopping power but requires a longer pull and offers better feedback about what the front wheel is doing before full lock-up. Braking on the track is under quite different conditions so planned one-finger braking using a firm lever is more desirable by some riders.
 
I don't know if I agree. ABS negates the panic locked up front wheel. An untrained unpracticed rider going full ham on the front brake lever won't be able to discern anything from lever feel, it never would have entered their thought process.

Maybe but the brakes not piling on as hard as they could might prevent some low sides into oncoming traffic in a canyon buzzing around a curve….

in any case I think they make the lever way too soft, probably because most riders don’t like a really hard initial first bite

I’m a pretty novice rider compared to most of you but after years of Motorsports I prefer a sensitive brake….I like tighter fitting thinner gloves and a lever that’s firm enough and sensitive enough that I can one finger it and still get good stopping power without a lot of lever travel.
 
Most of my new parts will go on later this month, but the new GP4-MS calipers are going on now.

so this weekend at Streets of Willow I’ll be running the Brembro RCS Corsa Corta set on Race, with the BREMBRO GP4-MS calipers and the Sicom Rotors and pads.

I also have a set of Magnesium wheels that I’m mounting T-Drive rotors and Z04 pads that I’ll run at the track day after that with the same MC and Calipers, will let you now how it feels either way.
