Reply to "Front vented rotor/hub combination option"

Don't worry too much about slightly larger than stock diameter rotors since the stock mounting of the calipers will position the pads in the same place relative to the axle centers. So ODs in excess of stock dimensions will not increase usable disc area to help stop the car, unless the caliper position is shifted outboard, too. And doing that may cause wheel interference if you're using Campys.....

Conversely, a bit smaller than stock rotors will cause a small decrease in brake capacity since the pads will overhang the rotor edge and generate a burr on the unused pad edge, as one owner mentions. On the street, you'll never notice either effect.
