I was checking out the brakes on my 01 camaro ss and noticed my rotors dont seem correct. They are Powerstop drilled ad slotted rotors and holes are bigger then the studs, also not centered. Will this be ok or should i replace them?

If they’re the correct p/n (obvious good first start) and the rotor fits tight on the axle (hub-centric) you’re good to go.

They were already on the car and they do not have a part number on them. The rotors can move all around on the lugs instead of staying in place

Grab it like a steering wheel. You can turn it left & right some due to the space around the studs right? But can you move the rotor up & down or front to back on the center hub? That's what Ramey is referring too.

That's normal. I have them on my car right now and that's the way the proper part came.

I could be wrong, but IIRC my rotors had no play to them.

Any car ive ever done rotors on rock back and forth a lil. Id guesstimate that the centrics i just did on my car had about 1/16 of an inch bigger diameter than the studs. Keep in mind after the wheel is torqued down, it dont matter the size of those holes, the rotor aint moving a bit

My OE rotors, as well as the Bendix replacements I later put on the car, had a little "clearance" around the lug studs, HOWEVER, the studs were centered in the holes, UNLIKE the one pictured.

To me, that rotor may be MOSTLY correct, from a diameter, thickness, centerbore, and offset standpoint, but I do NOT think the lug circle is correct. Note how the studs are contacting the outer edge of the holes, yet somewhat distant from the inner edge of the holes.
