Is there a written recommendation from ALFA to upgrade to 330? Or something like that?
Can someone please point me to some official paper by ALFA , my local dealer tells me that there is no such thing, and the original is enough..
To my knowledge, that's correct. There never was any "official" upgrade for the GTA brakes. It was just that later models, after a certain date, were equiped with the larger brakes (obviously because Alfa decided there was a need
). For earlier models, equiped with the smaller 305 brakes, the unofficial policy was that if people had problems with these (i.e. 2 or 3 times warped discs), the brakes were upgraded to the larger type, or alternatively, if the customer wanted, you could upgrade even without having problems if you payed an upgrade fee...
