I am in the process of removing brakes and rotors. 2011 non PP SHO. I have removed brakes and caliper, and then now trying to get rotors off.... the car spent 3 years up north before finding it's way to TN..... back of rotors is rusted like crazy. They won't budge..... I have taken a rubber mallet, and then placed a piece of wood on the rotor and took a hammer to it... still didn't budge. There seems to be a star bit on the front of the rotor.... is this for some reason screwed to the car somehow? I've never seen anything like it. I need help. A lot of rust has come off with me smacking the thing.... I have soaked the front and back with PB blaster. ..
