Driving down the highway and my front driverside wheel comes off, recovered the wheel and there doesn't seem to be significant damage to the rotor. One of the lug bolts completely sheared off so I need to replace whatever that plate is (I can't figure out where to find it). Also the shield like plate that is on the inner side of the rotor was what hit the ground and covered most of the damage. I attached a few images with the parts circled, any advice on what these parts are, where to find them, or repairs would be appreciated!
