I'm gathering parts for a full brake job. Receiving my rotors today, I noticed that the back has a tapered hole for the set screw SF605047. But the front is not tapered. How is the front retained? Just want to have all the parts ready before I start.

 

My fronts are countersunk. I think they didn't finish yours. But the screws were missing from my car and I haven't replaced them yet, and may not bother.

I promise you that once you tighten your wheel nuts, the rotor will not fall off! And once it has been on the car a few months, it wont even fall off with the wheel removed.
