I wrote an article on here a few months back on fitting new disks, unfortunately just before the change over when the site was down for a while, Its confusing when it comes to front disks. The V6 has 11 inch (284mm i think) disks which to my knowledge only fit the V6, The Older 4 cylinder cars have 10 inch disks which are not to hard to come by. Later 4 cyinder cars and those with the sports pack have 11 inch disks which are not the same as the V6 but are the same as disks for the Fiat Coupe. Ive got these on mine problem is even the alfa dealer wont know what your cars got unless you give them the chasis number of your car. Do this or get the wheel of and measure before you do anything. The 11 inch disks are well expensive like about £95 each at an alfa dealer. I ordered a set advertised for the fiat Coupe from Spares-HQ. Fit perfectly, worked out about half the price of the Alfa parts for these EBC ones with drilled patern. Disks seem fine although not sure if I'd recommend the drilled ones to everyone as I notice a bit of a buzz from them under hard braking and they require more pressure on the pedal to achieve the same braking performance, still they seem settled down a lot better now after putting 2K on them and Id say the braking is more progressive than it was originally and a little less prone to fade, although fade was never a problem I always found the grabby nature of the 155 brakes a bit awkward.
