[N55135i]

Here's an image of my Brembo install without the nubs. I have a few thousand miles on them now & I have not had any issues. My car is not a 135i so I can't use them to their full potential (weaker booster*). This is also why my brake pedal will always be softer too despite steel flex lines. Breaking from 200kph+ is however much more stable & shorter now on Autobahn.
