Design 90 Rims for '78 SC?

Yes, they will work but you need to know the correct offset of the SC and then use appropriate spacers for a proper fit. Offsets for D90's is 52mm BUT you mentioned 7 and 9 inch rims--D90's are 6 and 8. If not sure of the specs, check around the valve stem. You should find the rim width and offset stamped on either side.

Joey & Rol607,
I have some different information I recalled from reading Adrian's book (page 281) about D-90s listed in several sizes. It struck me when I first read it because I'd never heard of anything other than the 6"/8" combination. In fact they seem to have come (also!) in 7" ET 52.3 (964 362 112 01) and in 9" ET 52.3 (928 362 118 02). So it seems the 9" wheels (if Rol has Porsche wheels afterall) were originally intended for a 928? I can't guess when 7" wheels were fitted. Hope this helps. Joe W.

The D90s were never offered in 7 and 9 inches for the 964 apart from the Carrera 4 RS. They were certainly not offered on the Turbo which came standard with 7JX17 and 9JX17.
They may have been available for the 944 Turbo, 968 and 928 but I have never checked.
The D90s will require huge expensive spacers to be fitted to a 911SC. These wheels not only have a totally different offset they are somewhat wider than was ever fitted to the 911SC.
Legality for fitting such spacers depends on where you live. A location is not given for the original poster so I have no idea where he lives to give a definitive answer.
Ciao,
