Yes there casted. No I don't know if those will fit, they are for the 6 spyder diff's. I'm not sure if it will fit since the spyder size could be smaller with the 8 spyder's.

Worth a shot though.

But really, it take's some real effort to even damage those casted gear's. It's been done plenty of time's, but that doesn't mean you'll break it with a brushless set-up.
