Just a thought. If i use unoriginal wheels that require spacers could i then use original 930 spacers but adjust the offset with the wheel spacer?
I am thinking about running some 8 and 9 inch RUF rims (yes I know there heavy and this is stupid. Stupid is what stupid does).

Stock 930 rotors for '78-80 930 are 2 piece floating and can be used w/ stock SC hubs Stock '80 up 930 rotors are 1 piece and have a built in os that the earlier versions had a wheel spacer for. W/ the earlier setup the spacer is simply not used on an SC. '80 was a transition year.
I am unclear as to what spacers you referred to in your posts, there are caliper spacers that are used to center the caliper on the rotor and there are wheel spacers that are used to move n/b wheels outboard when they are used on w/b cars.
The 930 caliper bolt to the 3.5" SC struts but usually a small caliper spacer is needed to center it on the rotor.
You can use oe 930 hardware or buy aftermarket, VCI is a popular supplier of the rotors and accompanying adapters and hardware. They can also machine the rear calipers to convert them from 3.5" 930 trailing mount to 3" leading SC mount.
You can use either floating or non, the main complaint about the old style floating is noise at normal speeds.
