Guys, which brake disc style do you suggest? I've got plenty options to choose from. Drilled, slotted, drilled and slotted or dimpled and slotted. I've hear that drilled ones may crack and slotted ones tend to provide more brake dust than the ones without the slots. Also, I've got two offers. One is 230AU$ and the discs are from some random company. People have been happy though when I read reviews from the internet. Other company is Black Diamond and they're asking for double price. Is BD twice better aswell?
