whats involved ?

[speedy]

I used 996 disks that go with the calipers and a 5mm shim behind the disk to get the disk centering on the calipers correct , apart ftom that it was pretty simple , i don't know if anybody has mentioned it but my 996calipers were fitted to the front of the disk on the 996 so when fitting them on the back of the disk you will have to turn them upside down and swap the balance pipe to stop the shoes from wedging (different piston sizes ).Just somthing to be aware of.
