This doesn't really answer your question, but I would strongly advise against fitting el cheapo brake pads! eg. ferodo come in 3 varieities, Ferodo Target, Ferodo Premier and Ferodo DS2500. I would certainly
NOT fit target to any car I owned because they are dreadful.
The OE pads on most vw's are Lucas but actually made by PAGID, these aren't bad but for the extra £50 I would go for Ferodo DS2000 or Mintex Fast Road.
Here's a website which seems pretty cheap.
