Default Replace rotor hold down thingys?

Is it necessary to replace the washer like thingys that hold down the rotor when removing or replacing the rotor?

It appears that the wheels will do the job when they are installed.

You do not have to replace the washers. They were put there to hold the rotor in place on the assembly line.

Those should have been removed when the car was new at the dealer in the dealer prep phase.

Those washers are only needed in the car build to hold the rotors on before the wheels are mounted.

leaving them in place can cause problems.
OEM wheels have cutouts on the back that allow them to stay in place and leave the wheel flush and square to the rotor.
Some aftermarket wheels do not. That means they can act like a space and should you only have 1 or 2 on, they act like a shim changing the alignment of the wheel to the hub and cause premature tire wear problems.

You are absolutely correct. I am not telling this story to prove I'm dumb, but to prevent anyone from making the same mistake. When I put CCW Classics on my Z, I intended to remove the clips before installing the new wheels. With a friend "helping" me, due to talking and not paying attention, we put on all four wheels with the clips on. I suddenly had a terrible vibration at highway speeds above 60 mph I hadn't had before. I called CCW and said what gives, you sold me new wheels with tires mounted. I was asked, did I take off the clips? I replied that I thought so, but I'll check anyway. Well, after reinstalling all four wheels the car was smooth as glass.
