Something to understand, VAG tend to use firms like Textar and Pagid (same group of companies) and even Bosch, for brake friction material. I don't know who makes the discs though. ECP (and others probably), also source parts from elsewhere, and in a kind of naughty way, brand them with their own "company" name. Now as "we" tend to like Germanic products, they cleverly use a made up Germanic company name - that makes "us" feel very good about paying a lot less and still buy "German" made parts. By sticking with companies like Pagid, you are more likely to get a better compromise of cost and product - and Pagid do seem to be branching out into the greater aftermarket right now.
