Yeah, what Dave says..... the ones in that link aren't braketech and tbh look pretty poo. I wouldn't buy drilled and grooved as plenty are known to crack when they get hot. Grooved is fine.
These with the PF.11 pads will be much much better:

But 3 times the price.... as everyone says, you get what you pay for.
