Looking to change the rear discs on a BMW E91 and whilst looking on Eurocarparts Drivemaster discs currently have a 71% discount and are £18 each rather than £74.
However I've never heard of them and a quick google doesn't really help.
I've never heard of them but I can't imagine an £18 brake disc is up to much. Even with Euro Car Parts discounts, I'm sure they don't sell anything at a loss.
