The sheep will bleat but take no notice of them. They just pay their money and take comfort in the fact they are being told what's good. For 90% of people oem discs will be fine. How much worse can 1 lump of metal be to another?
E.g. Porsche oem pads are textar. They aren't cheap. You can buy textar pads from other places for like 2/10ths of the price. Are they any worse? No.
Same with oem discs or any plain disc. I bet a drilled disc is more likely to crack than a plain vented disc as the drilled one is weaker. How many people have had their oem discs fail or crack from road driving?
