Not uncommon after hard track driving.
That comforts me. I never had a car that has painted caliper, so I was little nervous about it. With SS braided line and DS2500 pad all around, the braking performance is not that bad. But I do feel a little lack of brake's capacity for the car. Also, later on that day, I felt vibration coming when I press the brake. I don't think the rotor is warped at this moment, it's more like uneven pad bed-in to the rotor..
Do you guys think 330mm conversion can solve all that? Since I'm in the country where there is no Alfa dealer, so I have to import the parts myself.. maybe from Japan? or even England?
I owned a couple of fiat coupe 20v turbos - Brembos are silver on them. On fccuk it was thought an achievement if you could turn your brembos from silver to gold - proof that you were driving to its limit!?
Haha that is funny.. True Italian Spirit there!

So the question is how to turn it back to the original color white letters on red caliper... anyone?
