Front rotor resurface

I removed the rotor to replace the studs. Is it a good idea to resurface the front rotors? If so does the hub need to be removed from the rotor?

Condition of the rotor. I had already drilled off the heads of the rivits.

Are there grooves in that rotor that you can feel with your fingernail, if yes resurface but you should do both sides.

Unless you have major scoring, I wouldn't. I don't routinely machine rotors anymore, even when replacing pads.

You didn't have to remove the rivets to resurface the front rotors, if they are not undersize and can be turned. In fact you may be opening them up for more runout. Rear rotors are a different matter but fronts are the same as any car of the period.
