I installed Brembo T drive 330mm rotors, Stylema calipers and Rcs19 corsa corta master. For the money I don’t think it was the improvement I was hoping for.
First thing I tried was an Rcs 17 master with stock rotors and calipers. The brakes had a better initial bite and feel than my setup now. Should have just kept that setup but I thought bigger the better. Not so much honestly.
Changing just the stock master to Rcs17 will give a lot of improvements for far less money, is my point really.
I do like my brake setup.I’ve got 14k miles on my bike and several track days and the brakes are awesome.
The RCS is really a street master -- note the brake switch, etc. I'm not sure what your application is, but if it's just track, in my opinion, the MK2 19x18 is way, way better. Much better feel, cheaper, fits easier on the bars, and is more simple. I think $240 for the non-folding leaver. The 18 / 20 mm stroke changeable option on the RCS(s) is kind a gimmick, as I don't know anyone who switches it (or anyone who runs the 20mm stroke, at all, for that matter.). I guess they don't offer a 17mm bore version of the MK2, so if you're really loving that, stick with it. And the silly new Corta thing is even more gimmicky: "normal," "sport," "race?" Give me a break. You say you like your setup, which is great, so this is just some food for thought for maybe next time.
Stock rotors should be fine in most applications. I won't be changing mine -- at least not yet. If I do, I'll keep the 320mm. I'll have to because of the rules, but even if not, I doubt I'd need the 330mm. I think you have to really be a fckn demon to be outrunning some EBC / T-drive 320mms. The 330's are just heavier and there are some other drawbacks.
I'd say most people are over-braked. They think in terms of absolutely stopping power; when really, it's much more about feel. As a point, I ran stock R6 HH pads in my Twins Cup bike for most of last year. I did end up having some fade problems, and had to change them almost every weekend, but the feel was way better than those Z Brembos or the XX Vesrahs that most everyone else was running. Just too much initial bite. It's of course preference, to an extent, but as a rule, I'd say you're better off with better feel than sheer brute force. I now run the SBS dual carbon which is kind of the best for feel, fade and longevity, but that's my opinion.
