Sorry to ressurect an old thread but about to do the above upgrade path on the brakes on my '55 FR TDi, 288mm => 312mm as discs need replacing.
I understand that the carriers need replacing, is this because the calipers need to be spaced further from the wider discs?
Do the carriers use the same bolts that hold the old carriers in place or are new longer ones required?
I've searched quite a bit but havn't been able to find this out.
Thanks in advance
