i am in the process of fitting brembo six pot fronts and four pot rears to my 103 12v 3.2 amg tt. i have the calipers,((from a sl63) but am short of funds to buy the discs yet. (1220 gbp)

i have researched the subject fully, and the brembo gt kits for the w210 list 355mm front and 320mm rear discs, that have the same part number as the w202, and w202 c36 brakes go on the 124, so the 210 discs should fit, apparently you need to use a pair of 3mm washers on the rear calipers to center them correctly

there are also 380mm front disks available, which may fit? watch this space.

or better yet, shout back what you find out...
