I recall that a BBer stated that those discs are 5*98 redrilled to 4*98, can you confirm this?Biba,
If, like me, you don't fancy the idea of redrilling some Milano discs/rotors, there seems to be a solution:
ALFA ROMEO ALFETTA GTV GIULIETTA FRENI MAGGIORATI | eBay
I have ordered a set last week. I'll let you know what I think once I receive them.
