Ive been looking at getting some new discs and pads for my 1.9 tdi 90hp, when i looked on the euro car parts site they say i should have 256*20 discs and i went out and roughly measured my disc through the wheel and thats what they seem to be, but then i went on the ebc site and they say i should have 239*20 discs. And all the listings on ebay seem to be showing that 239mm are the size that should be on although they do say td not tdi. VAG-CAT doesnt seem to list any 256mm discs which i know is wrong. so Does anyone know what i should have?
