After some research on different forums it seems like he is right.OE ones are not just rubber but are indeed SS braided lines wrapped in reinforced rubber.or is it just on the M3/M5's?

"People notice improvements in brake feel because they have new lines not necessarily better lines than the OE lines.change with OE and you will get the same feel"

Do you guys agree?
