With regards to hoses;
I have been told I do by some to get some by others there's no need but that it is a bit of a stretch. I will not do this conversion myself as wouldn't have a clue so don't really fancy paying a garage to get that far then have to put everything back.
Have you done this conversion on your FR teepee? I will proabaly be getting local VW master tech to sort this for me and he would know but worried about the cost.
job takes about an hour tops......i've upgraded brakes on quite a few cars
my old 8L A3, GF's 8P A3, My 120d now has 330mm set-up and yes the FR has big brakes. It's a doddle. The probs with TT hoses is the routing and clamps are different thats why i didn't bother. I bought a full set-up including hoses for my first A3 and still have them in garage unused.
They are available if someone wants them !
