those small metal retainers are stock... thats how the car came. You CAN remove them, however, leaving them isnt gonna hurt anything
What I'm getting at is that the back side of the aftermarket wheels may not allow for their thickness, and they are not letting the wheel sit flat against the rotor hat. That appears to be the problem we're trying to fix.
Another reason for removing those things is to prevent them from gouging up the wheels (and leaving a bunch of stress concentration pits).

Those would be called hubcentric rings... and their job is to center the wheen on the hub. I have never used them on my own cars, and I dont feel they are needed.
if your wheels are lug centric...then you will need the hub centric rings to center the wheel to the hub...if your rims are hub centric rims....you don't need the ring
