Drilled my first 2 rotors ever about 2 months ago.
Took the stock Fiero rotor, laid it on top of the new one and taped them together after making sure everything was good.
Then I just used a marker to fill in the holes.
Separated the two, then started with a small drill bit and worked up to a 1/2" or 3/4, I forget now.
Milwaukee Titatnium drill bits had it feeling like I was drilling through plywood
