I can't seem to get the T50 bolt off my rotor. Is it normal for the rotor to spin when I have the car on the jack ad I try and take the t50 bolt off??

 

Okay so I see I put two lug nuts back in and use a bar, but I am still having difficulty getting the t50 bolt out off the rotor lol

 

Had some on a VW once that didn't want to play ball.
Spray w/ PB Blaster or the like, let sit, then try an impact driver- the kind you 'tap' with a hammer.
I suspect that smart people won't like hitting a bolt in their rotor with a hammer but it worked well for me and so did the rotor afterwards.

 

I am also a fan of the hammered impact driver. This is sort of the situation it's made for. But you can also block the rotor from turning easily, and that is a good thing.
