I researched this route(in my case it would have been 25.00 per rotor plus studes) but was afraid the redrilling could compromise the integrity of the rotor as part of the webbing on the back of the rotor hub has to be removed in order to redrill. Not to mention the hassle of replacement parts. This way all replacement parts are OEM and available at your local parts store.
