I'm fairly sure they are.
People fit the same aftermarket discs on the 8v as the 8p so I would assume they are the same original part, but haven't had an 8v disc in my hand.
Drilled Mtec 1471 , silver protective coating, with the drill pattern selected to suit the fronts is one of the more popular after market parts.
The mtecs mirror the same dimensions as the 8p RS3.
