take a throttle body cover screw off and put it in vice grips and bam you have a tool. works every time. and when you get inside the opti to take the rotor off you will need some tiny torx bits

the inverted torx bit size was impossible to find for me so I ended up having a shop do it, shortly after I heard about the tb plate screw idea

It's called a E4 socket (inverted torx). I got one from my local Autozone. It had a yellow label.
