Is it okay to use new pads on my current OEM rotors? Is there something I would need to do to the rotors?

 

Yes.

No.

 

That was easy. Thanks.

 

Well actually if the rotors feel like their uneven, or small dips (run your finger along the rotor than you can tell) than you need to get the rotor resurfaced or replaced. Other than that you should be ok

 

What about the rings on the rotors? Are they consider dips or uneveness?

 

By "rings", I assume you're talking about concentric grooves in the surface. As long as these are moderate, they're no problem; the pads will quickly "bed in", wearing so that the surface of the pad conforms with those grooves.

If they're unusually severe - more like gouges - then the rotor may require resurfacing or replacement, as indicated above. But that's pretty rare on a street car.

 

Yes, they are the concentric rings I see when I stand next to the car while looking into the wheels. Can't tell if they are bad/deep or not but will try it later. Need to put on my Hawk pads, both front and rear. The front rotors are just 2 weeks old but the rear rotors are still the original rotors and the car has 13k miles now with 2 days track event. I toasted the front rotors (warped) after the 2nd day but I can't tell if the rear needs to be replaced too.

 

Rotors generally need to be replaced (a) if they're warped (as you already understand), or (b) if they're cracked or gouged (normally easily visible), or (c) if they're thinner than the spec; they wear down after a while.

With the number of miles you've got, I doubt that the rears need replacing. Track use puts almost all the strain on the front brakes, not the rear.
