I'm not sure what progressively sized pistons means, exactly but no - no need to worry about such extreme stopping power that you will slam your face into the steering wheel from a sudden stab at the brake pedalHaywireTig
Thanks nkgneto! Was v helpful indeed. How does it feel when u first used it. Does it slam down hard when u press the brakes a tad too hard... ie is it a jerky overly strong stop at the initial brake?
I read somewhere that the Brembo's have progressively sized pistons therefore doesn't immediately wanna slam down hard when u first brake. Is it like that too w RB brakes?
Honestly, it's very hard for me to say rather I have gained or lost anything (so I assume it's roughly the same) in terms of outright stopping power with these rotors / calipers versus OE. What I know beyond any doubt that I HAVE gained is very noticeably more linear, predictable, easy to feel relationship between pedal pressure and stopping power (mushy - WTF's happenin down there - brake pedal feel = GONE) and I have gained massively in terms of benefits related to reduced unsprung weight. I am very happy with the results and highly recommend this kit!!
As far as outright stopping power, pads make a big difference, and I have just fitted EBC yellowstuff up front (rear yellowstuff to be fitted soon). Very noisy at first, but starting to quiet down, and though I have not really pushed them yet, the difference is easily perceptible. I'm looking forward to having yellowstuff front and rear fully broke in - I'm thinking it will be EPIC - compared to stock - but it's still not going to slam your face into the wheel at the slightest touch of the pedal, so no worries there
