i ate half a week talking to every technician i know and the engineers from 3 fiat dealers.this was their replies:
the abarth brembos,only just one caliber,is worth 442 euros.for the 2 884 euros and that is without any adaptors,screws,arches and so so so.
now, there is a reason for writing the word adaptors.and yes the abarth brakes are fitted with adaptors on the powerfull abarth,just like any other after market brake.
after this myth busted for me i will go and fit my 4piston caliber from the carrera i have.and that's because i am sure :slayer:now that they will work.note that the abarth brakes are 2piston calibers.
