Here's a pic of one. Came with the car when I bought it. Needs new rings now. What brand are these? Where do u get new ones? Also never had 2 piece rotors...wat would be the tq spec and is there a certain procedure or sequence. I would think u would wanna use loctite? Any input, never did this before and I track the car so I wanna know the correct way.

You can eliminate Wilwoods as they have a different way of bolting to the hat. Can't really see in the picture any reason to replace the ring. There aren't any cracks and it looks like it is much thicker than minimum rotor thickness spec (slots would be worn away if it was approaching minimum thickness).

It isn't an AFX/Coleman rotor either as they also use a different bolting mechanism. I attached a picture of my cracked Coleman rotor.

Its got a nice ridge on the outside edge so I assumed its starting to getting thin. If an indication of min. thickness is the slots disappearing then ill put them back on and use them. However I would still like to see if anybody knows the brand, so I can order them when they do wear out.

Thx its money I can spend elsewhere for the car.

Not sure whose hats those are but those are deffinately coleman rings. If you measure them and call performance afx or hardbar or finspeed i am sure they can hook you up.

Those are DBA 5000 (Disc Brakes Australia) rotors, same as I have on my car. Rings are available from any DBA dealer and they come with new Nylock nuts.
Checkout KNS Brakes in Raleigh, NC - forum vendor - they have the best price on replacement rings I have found.
Installation requires a Tri-Y bit that can be hard to find and is expensive. Mine cost $22 plus shipping. It is like a phillips bit but with only 3 blades, nothing else will work.
Installation is easy once you figure it out. New mylock bolts are shipped with rings, one use only ! Use the tri-y bit to hold bolt and use ratchet to remove nuts. Install all new nuts on bolts finger tight and torque down in two rotations using a modified 90 degree star pattern.
I don't remember what the torque spec is right now, but it is included on instruction sheet with rigs. Torque spec is in INCH POUNDS or NEWTON METERS, you will need a small 1/4" torque wrench measuring inch pounds, your standard 1/2" ain't gonna cut it !
