Thanks to all who replied to my post especially fast5freddy,i am defo going to go new,i do agree with all your opinions on here that from time to time second hand kits come up on this forum and the bay,but by the time you buy them and have them refurbed and painted in gti red,id be just as cheap buying new i think.failing this i might get in contact with Dave the relevant brake guru on here lol.
to eveyone and thanks again
