97 M3-floating rotors or After market solid rotor?

Hi, a floating rotor has an alloy hub with spokes that attach to the
rotor,unlike the aftermarket rotor which are one piece. Hope that an
adequate description.

The "floating" rotor indicates a 2 piece brake rotor where the hub part
is allow and the disk is steel. I don't believe that anything actually
"floats" so I don't really understand the nomenclature myself, and I
also don't quite understand how isolating the steel disk on an alloy hub
improves the heat transfer, but that is the claim.

Here is what they look like:

Floating rotors are not intended to improve heat transfer. The purpose
is to allow thermal expansion of the rotor without causing distortion.
The rotor is allowed to expand as it heats up without directly
transfering the resulting strain to the hub.
