Default Rear Rotor Install?
Installing some aftermarket rotors (slotted/crossdrilled). Anyway, on the rear is like a "donut" or something that sits in behind the stock rotor, and has to be pushed back and not so "attached" to the aftermarket unit--is this normal? Did not know what to do when installing the rotors in concern to this issue. Thanks.

The rear brakes on the 1998-2002 f-body have a drum brake assembly inside the rear rotors for the parking/emergency brake. Is that what you are talking about? If so, then they probably just need to be adjusted so that the new rotors can slide on. But dont forget to re-adjust them after you re-install the rotors. The drum shoes should be in contact with the drum inside the rotor. On regular drums, you need to adjust them to have a slight drag (not free-wheeling), but I dont know about these.

And the fine quality aftermarket rotors he purchased may well not support the ebrake.

Drilled/slotted = appearance, not performance, and may hurt performance.

Can you adjust our shoes with the rotors still on?

Yeah, because putting holes/slots in a rotor really messes with the ebrake and fitiment.
